I know - it's really annoying but I've given up trying to discourage people from doing it. It seems that the 5-image-per-day maximum either just doesn't work or has never been put into place. Either way, one or two people are still doing it.
All I can say (apart from reiterating what has already been said in this thread:
http://forums.biorust.com/biorust-sp...ge-upload.html (Maximum Image Upload) ) is that people who flood the Gallery will find that they receive far fewer comments than those who limit themselves to uploading just a few choice images at a time.
