Several years back my site actually tried having each image get uploaded to a separate page, then displayed the gallery with listpages. This allowed for a deep level of control and interaction (images could be ordered random, have a perPage limit, could each have their own comments, and even other things like ads could be integrated into the gallery. We did this for thousands of images. Unfortunately, this was a nightmare in terms of user-friendliness since it is a very manual process to add images, so we went with a standard gallery for it's simplicity. People expect galleries to 'just work', so the simple approach was far better and more popular. I think the only downsides on Wikidot in terms of images are: 1.) the lack of a native automatic fullscreen HD image viewer (think Google+, Flickr) (medium size jpgs on the lightbox doesn't cut it in a time where we have 4k monitors and beyond). 2.) images are treated too much like files (no built in sorting, commenting, etc) rather than being considered as a separate entity. Again, I know this isn't solely a photosharing site, but it's something to think about when 'being more than just a wiki' :)
