When a member adds an image to their gallery, Cheetah replaces the Title or caption with the image file name if the poster fails to add their own title. This can lead to images having ridiculously long and stupid titles which can ruin an otherwise well presented gallery.
As some people may not wish to add a title to some of their photos, the simple solution is to make titles optional on the Add Photo (Video) page. Nothing is lost and they can always add one later.
Cheetah can still use the file name in the background to do all its chores.
Or if it needs to add a title, how about the user name plus the time stamp.
