I am making a site with PHP where users upload images for their profile. I already have that working just fine. However, I want the users images to be circles. From what I have read I believe that I can not crop an image into a circle, I will have to mask the image to make part of the image transparent. I have really no idea where to start. I would really appreciate it if anyone could point me in the right direction, or maybe even some sample code!!!
You don't have to actually edit the image if you have a consistent page background. Fake it out like so...
<div style="width: 50px; height: 50px; background-image: url('path/to/user/image.jpg'); background-position: 0px 0px; background-repeat: no-repeat;">
<img style="margin: 0px; padding: 0px; border: none;" src="path/to/circle/mask.png" alt="" />
</div>
You could put quite a bit of this markup in your stylesheet too (to clean it up).
Just save the image as a square, and use rounded corners to crop the image.
You will set the image to be a background image in a div, and set the CSS to have rounded corners (enough to make your div a circle). You can use PIE to make this CSS mark up work on IE 6-8 as well. See the PIE site for more details.

I'm working on a small project, and have one little problem that I don't know how to resolve myself. I have an image gallery with many images, but I want the active image to be centered, without changing the resolution or width/height ratio. Link for the issue here. Login is user / password. I tried to manipulate with this CSS:
.img {
margin-left: 200px;
}
However, it seems to ruin the bottom slider. What should I do to center the main image without changing the image ratio? This example image shows what I want to do.
Try this
.imgs {
margin-left: auto;
margin-right auto;
}
or you could do this
<div class="imgs" align="center">
<img src="https://source.unsplash.com/random/200x200" />
</div>
Try adding:
.flex-active-slide {
text-align: center;
}
i'm with a trouble in relation with treatment of image, using intervention image on laravel. The problem is: I have to change aspect ratio of a image, but, in my current way, i'm cropping the image to do it, and important things in this element is being cropped too. So, i was wondering, is it possible add border around on image to create the aspect ratio? If you all would can help me, i'll would be very glad with that.
P.S. Sorry for my english, i'm still learning, haha.
Solution 1
Create a div with the right aspect ratio/dimensions and load the image as a background image with background-size: contain.
div {width: 300px; max-width: 100%;}
div > div {
width: 100%;
padding-bottom: 60%; /* use this for the aspect ratio */
background: black url('http://jekyllcodex.org/uploads/grumpycat2.jpg') center center no-repeat;
background-size: contain;
}
<div><div></div></div>

How it works
The padding bottom creates the height for this div (as it has no content). The padding-bottom percentage is the percentage of the width of the parent. Thus, a 2:1 ratio image has a padding-bottom of 50%. A 3:2 ratio image has a padding-bottom of 66.66%.
Why this works
The div inside this div has a width of 100%. This is 300px, as the child div is constrained by its parent. The padding bottom percentage is relative to containing block, and not (as many people think) to the body. Here the containing block is the nearest block-level ancestor, which is the parent element. Note that it would be relative to the body if we used just one div with a fixed width of 300px.
Why this solution is not perfect
This solution is fully responsive, due to the max-width of 100% on the containing div. And if you change your mind and you want images to be cropped instead of contained, you only need to change the background-size to 'cover'. Therefore this looks like a good solution. However, a background images is not a proper image, as it has no 'alt' text and lacks a DOM representation, resulting in all kinds of accessibility problems.
Solution 2
Create a div with the right aspect ratio/dimensions and load the image as img tag with max-width and max-height.
HTML
div {
width: 300px;
max-width: 100%;
position: relative;
}
div > div {
width: 100%;
padding-bottom: 110%; /* use this for the aspect ratio */
background: black;
}
div > div > img {
max-width: 100%;
max-height: 100%;
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
<div>
<div>
<img src="http://jekyllcodex.org/uploads/grumpycat2.jpg" />
</div>
</div>

About this solution
It works roughly in the same way as the previous one, but this solution is semantically correct. The difference here is that an image element is positioned absolute in the inner div. Its placement is absolute, but relative to its parent at 50% of the left border and 50% of the top. Then the image placement is corrected for its width and height, using the translate function of CSS (otherwise its top left corner would be in the middle of its parent). Because only max-width and max-height are used (and not width and height), the image stays responsive and keeps its aspect ratio.
I need to fit and crop the image into it's wrapper.
<div class="box desktop-3 tablet-3 tablet-ls-3 mobile-3">
<div class="inner-box fullbox">
<a href='#module'>
<div class="image-wrap" >
<img src="../img/placeholder.png" />
</div>
</a>
</div>
</div>
css
.box {
width: 282px;
min-height: 282px;
padding: 10px;
float: left;
}
.inner-box {
width: 100%;
min-height: 282px;
top: 10px;
right: 10px;
bottom: 10px;
left: 10px;
padding: 20px;
}
.fullbox {
padding: 0px;
}
.image-wrap {
...
}
i've tried to put the image as the background like you see below, but that didn't worked for me. I want to have a image section from the image that it fits into the box.
.image-warpper {
background-image: url(...);
background-repeat: no-repeat;
background-size: contain;
}
Do i have to crop the image via php or is it possible to scale or crop it in css?
Thanks
"Do i have to crop the image via php..."
Depending on the Image file-size its strongly recommendable to use PHP for this purpose.
Remember the clients browser will always load the complete image to resize it to the css given values.
So even if you got a style telling the image shall never exceed 100x100px the client's browser will load the full size image.
That could take "very long" if its a giant image (referring to the file size).
There are pretty nice classes/libs you can use with PHP to get a comfortable and easy way to play with images. And your page will be much faster then.
For example i recently found:
http://wideimage.sourceforge.net/
Super sweet thing. Supports chaining and stuff.
You should be able to do this:
.image-wrap img { max-width:100%; height:auto; }
This will constrain, and scale down the image, and set it to be 100% wide, according to however wide the parent element is.
Having in mind that you'll use an img html tag, make the image wrap div in position:relative and overflow:hidden and the image with position:absolute and height:100%, width:auto (or width:100% and height:auto). This way the image will be cropped in the parent container and keep its ratio.
See this demo and resize the frame to see how the image is cropped and resized in various dimensions.
I am looking for something that would allow me to render an uploaded image with a 3D perspective and a wrap effect like here.
This will be in the form of a cropping preview using a jQuery library such as jCrop
Currently I was able to achieve the 3D perspective using Reflex.js but looking for a more subtle solution with the wrapping effect as well.
Any help will be appreciated :)
Thanks in advance!
Your requirement of IE9 support basically mandates a canvas approach if you want to keep it client-side. You could of course do the rendering server-side and AJAX load the rendered image back in which will work in every browser.
If you decide that you can dump IE versions less than 10 (or at least just show them the normal photo without the transform then you can do the wrap-around effect with a combination of CSS 3D Transforms and CSS2 clip. Something like:
<!DOCTYPE html>
<style>
body { margin: 100px; position: relative; }
.edge { width: 20px; height: 196px; background-size: auto 100%; position: absolute; left: 30px; top: 2px; transform: perspective(600px) rotateY(-45deg); transform-origin: right; }
.panel { position: absolute; left: 31px; top: 0; clip: rect(auto,auto,auto,20px); }
.panel>img { width: 350px; height: 200px; transform: perspective(600px) rotateY(30deg); transform-origin: left; }
</style>
<div class="edge" style="background-image: url(my_image.jpg)"></div>
<div class="panel"><img src="my_image.jpg" /></div>
To break that down, we’ve loaded the user’s image and dropped it into the page, along with a div with the same image set as a background. That div is set to be a thin width and a height that’s almost as tall as the main image. We can use the background-size property to foce the background image to fit the div even if it’s taller.
We then absolutely position those two so that they’re next to each-other. The CSS2 clip property lets us clip off the left 20px of the image so that at this point the div and img look like one image together.
Finally, we set a perspective and transform-origin for each block and rotate them away from each-other around the Y axis. Because of the clipping we have to fudge the .edge block to be slightly smaller than originally (with a 200px tall image I had to drop it to 196px to look good) but that works pretty nicely for me.
Obviously you’d need to fill in the vendor prefixes (-moz-, -ms-, -o-, -webkit) and I’ll leave the shadow as an exercise for the reader (a simple background on the container would probably do).
I want to improve one of my Facebook apps by allowing the users to apply border styles to their images. I am not exactly sure how this can be done, but hopefully someone here will be able to help. The application is written in PHP. I originally thought that I would be able to create an image with just the border, a few pixels wider and taller than the image I wanted to add the border to, then just merge the two images, but that didn't work.
Any help would be great, and rewarded with your name and Stackoverflow profile image postedon the Credits page of the app.
Try putting the background image in the CSS background property.
How about some code using random images from google searches?
<div id="myWrapper" >
<img src="http://www.iconarchive.com/icons/rokey/the-blacy/128/secret-smile-icon.png" id="myImage" />
</div>
<style>
#myWrapper {
background-image: url(http://images.clipartof.com/small/210747-Royalty-Free-RF-Clipart-Illustration-Of-A-Diamond-Plate-Border-Frame-Around-Blank-White-Space.jpg);
width: 450px;
height: 450px;
}
#myImage {
margin: 160px 160px;
}
</style>
Note: I don't claim these images. I'm just saying this cos somebody's gonna bitch. Watch and see ;)
EDIT
I see now however that maybe he does just want to add a style as another poster suggested. So now we're back to asking the OP does he mean how does he store user preferences for images and then dynamically add that style onto an image as it's posted from the app?
I guess that would call for an inline style wouldn't it? ;)
myImageSource = "<img src='".imgSrc."' style='border: 2px solid ".imgBorderColor.";'/>";
Assuming you're using GD to create the images, you can use imagerectangle() to put a border around the image. PHP.net has a great example: http://us2.php.net/manual/en/function.imagerectangle.php
#drachenstern: CSS is a good idea, but how would the background help? CSS has a border property that can be used. ;) img.someclass { border: 2px solid black; }
