Hi - I just wanted to say thanks for WP-Cycle, it came in really handy! The site I am working on required a caption so I tweaked the plugin a little, giving it an input field for a caption, which then is put into the image's ALT attribute. I then added a few more lines to the jQuery part of the plugin so the caption would display in a P tag beneath the image.
This is the first time I've ever modified a WP plugin, so I'm not sure what the etiquette is but I heard that it's polite to let an author know when you've done it. I can send you the modified code as well, if you think you can use it.
