I'm currently working on a blog for someone that has been designed by someone else. The design has the main index page listing articles from the blog. At the top of the design there are three buckets where the latest stories are and they all include an image from the article.
The images all have to appear at the same aspect ratio from the article when on the index page. Yet I cannot guarantee that the user of the blog (the article author) will take the time to make sure the image is the right aspect ratio to be scaled on the home page.
Does anyone know of any techniques to get around this issue?
It also needs to work across all browsers.
You can use TimThumb which can both resize and crop it to the right aspect. It is really good!
timthumb - image crop zoom resize management
So, these boxes will display post's plus their featured images as thumbnails? Is that correct?
You could use the get thumbnail hook, and set the dimension in the functions.php file.
But it really depends on your currect code.
Are the boxes using a post loop?
An chance of showing the current index.php code.

I have a question about wordpress slider plugin Cyclone2.
Problem is that when I upload and add an image to slider, it outputs incorrect src url for img tag on site page, like adding slider width and height to image url..
Ex. I upload image Champagne-All-Bottles.jpg.
In admin panel image loads successfuly: /wp-content/uploads/2015/12/Champagne-All-Bottles.jpg
but on site page it adds a width and height to img url like: /wp-content/uploads/2015/12/Champagne-All-Bottles-1200x400.jpg
HTML admin panel(correct):
HTML output on site page(incorrect url):
This plugin probaly makes an 1200*400 picture copy of the one you are giving because somewhere in the settings you say that the slider should be 1200*400 pixels. So the plugin is transforming your picture to the dimensions of the slider. Is there somewhere in the settings of the plugin something where you can adjust the dimensions?
A lot of WordPress plugins do this, and even WordPress itself is doing this. Making different dimension copies of images you upload.
EDIT: I searched the plugin you are talking about and in I think in basic settings the "width" and "height" are there so you can change the dimensions. But one thing, all images uploaded will get the same dimensions, thats how this (and a lot of other) WordPress plugin works.
Note: if you set "Width Management" to fixed, the plugin probably stops resizing your image, can you give it a try?
-Resize Images?
-No, shut up!
#TotalCare, thank you for your help :)
I'm resizing larger images contained in posts for my site teasers using ImageCache (Drupal 7), and for some reason the quality of the images goes down significantly when I size down (e.g. 670x400 pixel image is sized down to 220x185). Quality doesn't usually go down when sizing an image down (only when sizing up?)
Does anyone know how I can fix this?
Thanks.
In back-end, under Configuration/Media/Image toolkit you can set the JPEG quality.
URL is:
/admin/config/media/image-toolkit
You can set a specific image style (image cache) preset for the node teaser from content type Manage display page. e.g. ?q=admin/structure/types/manage/[CONTENT_TYPE]/display/teaser
Click the gear icon next to the image field, and choose the image style you want to apply to the content type's teaser display.
I'm using regular imagefields on various content types in a Drupal 7 social website (and also on the user profile pictures via http://drupal.org/project/imagecache_profiles). For cropping I'm using http://drupal.org/project/imagecrop as an image style effect.
I would like to replace the original image with the one generated from the imagecrop style. How do you replace the original image from a user (the one that gets used for subsequent image styles when you say call it in views) with one that is created from an image style effect?
I'm not sure the best way to approach this problem, which is why I posted question.
To make sure I'm being clear -
A User uploads a large image (say 2,000 pixels by 1300 pixels) via a regular imagefield.
Using image styles, I perform some effects (specifically javascript crop, but this could be generic) and then replace the original image with the one generated from the image style.
All additional image styles (different sizes etc) use the new original images and are derived from it.
I think this can be done easily using a custom module and they must have used something like the image editor project - See drupal.org/project/imageeditor, just not sure what hooks to use or how to jump in on this. Any advice, tips or direction would be great.
Check module - Original image with style
I believe you can address your problem by making changes under the display settings for your field:
/admin/structure/types/manage/[your content type machine name here]/display
I need a way to automatically generate a thumbnail of the target page when the user hover over a URL (hyperlink) on my page.
I've found several examples of people using pre-created .gifs (or other images) to show a thumbnail of the target site while hovering over the link (see example #1), but I need a way to do this dynamically. Is there a way to generate a thumbnail of a page, either on runtime, or an easy way to update the current thumbnail after editing a page?
Simply put; I need to show a thumbnail of the target page when hovering a hyperlink on my page. This thumbnail should not be based on an image that I have to generate myself after each edit, but rather a snapshot of the current page. Much like google does when searching for websites.
Thanks a lot in advance!
Example #1:
http://www.dynamicdrive.com/style/csslibrary/item/css-popup-image-viewer/
Hover your mouse over "Zoka Coffee"..
Try to study about this library html2canvas
Frankly I am not sure where this would go but I assume the way to create what I'm about to describe is PHP... so I'm sorry if it's in the wrong section.
Basically I have a website, using Wordpress, where users can review websites and post a 5 star rating of the site. Each reviewed website has it's own dedicated page.
So what I want to do is create an image from the statistics of the ratings to allow the website owners to place it on their page. The image will need to, when clicked, go to that it's review page.
So the image would be about 150x150. Have the overall 5 Star Rating, the Name of the Reviewed site and the name of my website. It would also be cool if there was some automatically generated HTML embedding code so the site owners can simply copy and paste it.
I hope I explained myself ok. I've tried searching google but I'm not entirely sure what to search for and therefore have found nothing useful.
Thanks.
EDIT
I can create the embed code manually. I just need to really know about how to make the picture update automatically.
Hey what you are asking for is quite complex and it would be to easy to just give you code. So here is some reading for you. Your problem is quite meaty and no doubt you'll learn loads sorting it out....

I just need to really know about how
to make the picture update
automatically.
Just put URL to your php-script, which will generate image.
You will need function imagettftext to write text over the image, imagecopy to draw the stars (of votes).
Also, you will need image of a star and background.
So, approx. algorithm will be:
1. Open the background image by imagecreatefrompng - it will be our generated image
2. Open the Star image
3. Write title of the reviewed site by imagetttftext
4. Draw stars by copying existing Star image to our background image (by imagecopy)
5. Print generated image by imagepng
