Hello bb,
I use colorbox extensively on our site successfully.
It looks like you’ve got some path-file mismatches. Your colorbox script is working fine, but it’s not showing you the result, because it’s looking for the files in the wrong places.
Take a look at this file:
http://aidsresearch.org/colorbox/colorbox.css
All of the references to your images are using “relative” paths (it tries to find the file “relative” to the current location… BUT because ExpressionEngine uses URL segments to load the correct template group and template, the browser tries to find your images in directories that just don’t exist - sorry, if my explanation is confusing… it’s a simple issue, with a complex explanation)
For example, in colorbox.css you have this code:
#cboxOverlay{background:url(images/overlay.png) repeat 0 0;}
Your page is not finding that overlay.png anywhere (I poked around with different paths and couldn’t find it either…)
Each of the images in the css should use paths that are relative to the root of the domain:
#cboxOverlay{background:url(/images/overlay.png) repeat 0 0;}
Or you might organize your files with a little bit of structure to help you out:
webroot -> index.php
/themes/
/system/
/assets/images/colorbox/
/assets/css/colorbox/
/assets/js/colorbox/
This way, you can keep things clean and organized - which will save you much heartache down the road (my structure is fine, there are plenty of other ways to organize your files - however you see fit)
....
To start troubleshooting your issue:
1. Use a browser with some developer tools (Chrome, Firefox+Firebug, Safari)
2. Watch the developer tool called “console” - which is a useful method of seeing exactly what is going wrong with your page.
3. Also take a look at the “network” tab of your developer tools - this will show you what was attempted to be downloaded… and (more importantly) what failed to download. This is the key indicator to check that files are being looked for in the right place and being downloaded.
4. Ensure your colorbox files are on your server.
5. Update your colorbox.css to download the files correctly.
Let us know what you find, and if you need any further guidance.
I hope this helps
