Curious if you ever thought of making a Video Gallery or adding video support to this?
I currently use Coppermine Gallery over on a different website of mine, but would love to switch that whole site over to WordPress if I could get a good photo gallery/video gallery going. So far all the video galleries are completely lacking here. Coppermine can't integrate and their support is severely lacking.
With Coppermine, I'm able to upload my own FLV videos and also embed YouTube videos and each video has a description and thumbnail. Here is my gallery:
http://www.campblood.net/gallery/ if you go to http://www.campblood.net/gallery/thumbnails.php?album=69 (for example) and click on any of those you will see how the FLV's work, and if you go to http://www.campblood.net/gallery/thumbnails.php?album=67 you can see how the YouTube video's work.
I haven't been able to find any sort of WordPress plugin that does both FLV & YouTube with thumbnails. It would be awesome if you were to ever make one or add video support to this existing gallery.
