I am the author of the jQuery Colorbox plugin.
My plugin relies on a CSS class of images being set in order to activate the colorbox for them and to group them in the colorbox.
It would be really convenient if there would be an easy way to add a CSS class to the images of a gallery.
It would be even better if you could include my plugin in the list of lightbox clones to select from and add
class="colorbox-<?php echo $gallery->ID ?>" to the image tags automatically.
P.S.: One of the users of my plugin mentioned here that it would be possible to change the plugin template and add it to one's theme, but many users are not very tech-savvy, so I fear that only a very small group of users would actually be able to do that...
