Shadowbox PHP Facebook Graph Api Error - php

i'm using shadowbox for my website to open the big images with clicking thumbnails as you know. My Problem is, i'm fetching the users' facebook profile photo like :
$large = "https://graph.facebook.com/{$id2}/picture?type=large";
$small = "https://graph.facebook.com/{$id2}/picture?type=square";
And it's working perfect, but in shadowbox i have problem with large image..
I'm calling this in shadowbox like :
<a href="<?php echo $large; ?>" rel="shadowbox">
<img style="max-width:50px; max-height:50p;" src="<?php echo $small; ?>" />
</a>
As you can imagine, small image is showing perfect, but when i click on the small image which has href, it fails to show the large image.
I've tried to change large image variable to this :
$large = "https://graph.facebook.com/{$id2}/picture?type=large&redirect=false";
but also it has failed to show the large image..
Hope you can help, thank you

I haven't worked with Shadowbox before, so I don't know how it works behind the scenes. It may be that it can't deal with a url that returns another url for the large image.
Try making the API call with php and then passing this result to shadowbox.
$large = file_get_contents("https://graph.facebook.com/{$id2}/picture?type=large&redirect=false");
Of course, using file_get_contents() like this is a quick and dirty method. If it works, before you roll this out to a production site, you'll want to use cURL or better yet the Facebook PHP SDK to do this.
Assuming you're using shadowbox to show multiple users' photos on a page, you'll probably end up bumping into the API limits at some point. To prevent this, redo your API calls to grab multiple photos in one shot:
$large_photos = $fb->api('/picture?type=large&redirect=false&ids=' .
implode($ids_array, ','));

https://graph.facebook.com/{$id2}/picture?type=large&redirect=false basically returns you a text content the URL of the image. That's why it's not showing.
Eg.
https://graph.facebook.com/yungsenriady.budiman.3/picture?type=large&redirect=false
returns
"https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash3/157348_100001167523294_1569184886_n.jpg"
Try just use
https://graph.facebook.com/{$id2}/picture?type=large

Getting large thumbnail photos from Instagram is no longer working with "replace"

For long time I use this "replace function" to get the thumbnails by Instagram API, it worked well but now they changed somethings and I no longer to use bigger thumbnails by this way.
src="<?= str_replace('s150x150/', 's320x320/', $post->images->thumbnail->url) ?>">
By default thumbnail, it works well.
https://scontent.cdninstagram.com/vp/94387bd7b8a247f3f4039f8789772142/5AEE2A9E/t51.2885-15/s150x150/e35/c0.135.1080.1080/26335890_2247807142112483_5882778660510892032_n.jpg
But replaced thumbnail size to bigger, it appears a msg: Invalid URL signature.
https://scontent.cdninstagram.com/vp/94387bd7b8a247f3f4039f8789772142/5AEE2A9E/t51.2885-15/s320x320/e35/c0.135.1080.1080/26335890_2247807142112483_5882778660510892032_n.jpg
Anyone can help to get bigger thumbnail of Instagram. They changed API and I feel so tired with Facebook, they have made many changes since sync with FB and everytime like this, the developers have to update with no instructions.
You can try with this trick
src="<?= str_replace('s150x150/', 's320x320/', str_replace('vp/', '', $post->images->thumbnail->url)) ?>">
or
src="<?= str_replace('s150x150/', 's640x640/', str_replace('vp/', '', $post->images->thumbnail->url)) ?>">
You have to replace (delete) also "vp/" on url, and works again.
It's a really bad solution, but it's the only that i've found.
Copy the link of the profile pic after the "/s150x150/xxxxxxxx......jpg" to the end of this:
"https://instagram.flju2-1.fna.fbcdn.net/vp/e890a9f0b7b40abe5667b06d0fa750e5/"
like: https://instagram.flju2-1.fna.fbcdn.net/vp/e890a9f0b7b40abe5667b06d0fa750e5/xxxxxxxx......jpg
Works right now.
A solution would be very nice!
I have also done it like you the last few month.
I think one of the solutions is to use non-squared fotos from instagram (you get with "standard_resolution") and set it as a background-image and do the "square" via css and display cover… 
This is my personal solution at the moment… 
i opened instagram on google chrome selected the desired post, right-clicked to "save as". after opening the saved html doc. in chrome i right-clicked again to veiw page source. i scrolled down to line 217 of the page source and one of the links there gave me the picture i wanted. not sure that it is the same thing as before but it let me download the picture of the post in a .jpg format. hope this helps

Calling a gif with createimagefromgif in PHP

I've been trying to display a gif image using PHP and have not found a solution to my problem with the research I've done. I know I can display image in HTML/CSS, but I need to use php in this case.
<html>
<?php
$img = imagecreatefromgif("http://www.mysite.com/images/timer.gif");
?>
<img src="<?= $img ?>" alt="timer" />
</html>
That code resides in a php doc on my server. I can tell the code is working because an icon of a torn image displays on my site, and when I attempt to save the torn icon image to desktop, the automatic file name appears as "Resource id.html"?
I read somewhere that creating gifs with Photoshop CS5 (as I did) uses a different frame separator sequence, \x00\x21, instead of the official standard \x00\x2C. The guy then said he uses pattern "#\x00\x21\xF9\x04.{4}\x00(\x2C|\x21)#s" to bypass that issue but I have no idea how/where to implement that or if that is even my issue (tried a different gif from internet and had same display problem). Thoughts? Thank you.
Imagecreatefromgif() returns an image resource, which you can't use in this way.
Have your PHP script output the image data, with the correct headers (see example here http://php.net/manual/en/function.imagecreatefromgif.php).
Then you can call your script just like you would any other image:
<img src="http://www.mysite.com/images/generate_image.php" alt="timer" />

How to show a loader image in the mean time of the image get retrieved from the server?

I have a product gallery in which the product images will be retreived from the server and shown. It takes sometime for all the images to be retrieved and displayed. I want to show a loading image until the image is rendered from the server.
I have tried as below, by giving an if condition to display a loading image until the image tag gets its source. But its not working, as it just shows a blank space until the image get retrieved from the server.
if($image)
{?>
<img style='Max-width:180px;' alt="Nike Women Sweet Classic High Purple Casual Shoes" src="<?echo $image;?>"><?
}
else
{?>
<img style='Max-width:180px;' alt="Nike Women Sweet Classic High Purple Casual Shoes" src="media/images/snake.gif">
<?
}
Please tell me how can i make it work as expected
Well, you'd have to use JavaScript to update the DOM as you'd like to, as PHP will only process the page once. Doing so would mean switching to AJAX to retrieve the images, though, and that feels a bit like overkill for your scenario. Instead, why not give each image its own container, and then give that container a class with a loading image as its background? Then. once the image has loaded, it displays over the previous loader.
You can not do that on the server side alone. One would need to first load simple "snake" images on the php side:
<img style='Max-width:180px;' alt="Nike Women Sweet Classic High Purple Casual Shoes" src="media/images/snake.gif">
and then through javascript (ajax requets) update all the images like so:
// populate imageList
$.ajax({
url: 'your_server_script',
data: imageList,
success: function(response) {
// update teh src property for the images here usign your server response
}
})
As #ranksrejoined pointed out, however, you might be better off using css to give images a container with widht/height and background image. Then that one gets overridden by the image itself.
I think this is what you need: http://jqueryfordesigners.com/image-loading/.
I think you're suggesting an asynchronous load of the image - you may want to use JavaScript for that. Something you may like to try as alternative, is to apply a background image to a container for each child image.
<div style="background-image: ;">
<img />
</div>
Since lowsrc is deprecated, my best next choice would be Lazy Loading.
That means you only load images that can be seen on the screen right now, and not the images that the browser chooses to load, which can be down the page.
If you use JQuery, then take a look at the nice LazyLoad plugin. Definitely going forwards this time :)
Suggested implementation
you would load the jquery plugin, and write your images like this :
<img data-original="<?php echo $image; ?>" src="media/images/snake.gif">
and let the plugin do the hard work
Hope it helps !

link with same url in php

I have some thumbnail images with its larger version.I placed the thumbnail images in a page.Now for link I just gave a link
<img src="thumbnail1.jpg>
but for this I have to make different pages for showing larger one.I want to give a link to show them in a single page.means whenever I will click the thumbnail it will open the larger one in a page with the same url but with its name like
imagegallery.php?news=images/largerimage1/13.jpg
imagegallery.php?news=images/largerimage1/14.jpg
so how to do that?
Pretty basic stuff, I suggest you get to read some PHP tutorials on the internet to get some knowledge on one thing and another.
The ?news= part in your URL is a parameter that can be read by PHP. This type is known as $_GET. To get this part you would need $_GET['news'] so if we'd use your first link and place this inside a script: echo $_GET['news']; the page would say images/largerimages1/13.jpg.
In order to get the image loaded on your website we need some simple steps, I'm changing the news parameter into image, that suits better for your script since it ain't news items:
<?php
// Define the path (used to see if an image exists)
$path = 'your/absolute/path/to/public_html/'; # or wwwroot or www folder
// First check if the parameter is not empty
if($_GET['image'] != "") {
// Then check if the file is valid
if(file_exists($path . $_GET['image'])) {
// If an image exists then display image
echo '<img src="'. $_GET['image'] . '" />;
}
}
?>
Below this script you can put all your thumbnails the way you want. Ofcourse, also for these thumbnails there are some automated options. But I strongly suggest you get a good look at the script above and some beginner PHP tutorials so you completely understand the example given. This still isn't the best method, but it's kicking you in the right direction.
if your imagegallery.php is in root of your domain, you can just add slash as a first char to links like this:
<img src="thumbnail1.jpg>
else you will have to write some php function which it returns BaseUrl of your web. Then it should looks like this:
<img src="thumbnail1.jpg>
maybe you can something like this,
Techincally, there is no thumbnail image, just a stretch version of the regular image
I don't understand which part you don't know how to do:
- the link part?
it should look like
<img src="thumbnail1.jpg>
- or the PHP part (the file called imagegallery.php)?

Long (5 second) DOMContentLoaded wait when opening PHP file

Thanks in advance for your help with this. I've got a very simple PHP file that returns HTML code for an image based on some passed parameters. The code works fine, and the image shows up quickly. However, the page itself doesn't finish loading for a good 5 seconds, which is interfering with some AJAX calls I'm trying to do. Firebug says the time breakdown is like this:
0ms: DNS lookup
0ms: Connecting
0ms: Queuing
211ms: Waiting for response
14ms: Receiving data
+5.32s: 'DOMContentLoaded' (event)
+5.33s: 'load' (event)
Here's my PHP code:
<?php
$getimage = $_GET['p'];
$getcity = $_GET['c'];
?>
<img src="/images/photos/big/<?php echo $getcity; ?>_<?php echo $getimage; ?>.jpg" alt="" class="gallery" />
Pretty simple, no? Any idea what's going on?
This page is using "/images/photos/big/" which I assume means it's using a "big" image. images take time to render, this is likely the slowdown.
you might be able to speed this up by setting the image height and width because the DOM will not know where everything is placed until the image size is known. I am not positive if this will fix the problem, sorry.
