Advanced attached image display

[hulubei]

Hello,
I run a forum for beginers in photography. I would appreciate if someone could write a hack that all the images will be displayed in a window with black or dark-grey background and it will also contain infos about EXIF data (digicam, ISO, WB, focal length and aperture for example).
It will be also very nice if there can be added a way that to every photo, users can post comments on it so the forum won't be full of small comments for every photo. For now, we use the reputation sistem (with no altering power), but it's hard to remember allways to sign when you "add reputation" to the user. Also, the other users can't read the coments so they can't learn from them.

Sorry for my English.
