Here is an animated GIF which I created in Photoshop, duplicate the main picture you want to work with, you can manipulate the image in any way you like. Next bring up the timeline and put the images on. You can change the number of seconds and loop forever so you don’t have to refresh the page.
I have also assembled a bunch of images for use on Coda, you have to match all the image files to the folder they are in otherwise you don’t get the desired result.
Here is an example:
<link rel=”stylesheet” type=”text/css” href=”shadowbox/shadowbox.css”>
