Doing research on how lightboxes are controlled, I found this http://extensions.joomla.org/extensions/photos-a-images/photo-gallery/9512
Rounded corners, styling control over background colors, text descriptions. Would be really cool upgrade to the Flickr gallery in Wikidot.
I've paid for the Art Sexy Lightbox tool, but not sure if it will be suitable for my purchases (haven't got activation key yet), since they seem to want $20 / site and I create content for my subscribers but have a lot of wikis. Hopefully I don't have to buy for each site since the admin of doing so would be stupid. Without going in to the busines model, my customers sign up for 10-15 sites at a time… and each would need its own license since each has its own name.
And all I really want to do is control the Lightbox appearance of the Flickr galleries of each to make the navigation and text be a bit different.
