We currently have three areas on FlyerTalk where members can post photos: The Picture Gallery, Travel Photography Forum, and Trip Reports. The moderators for those areas have all reported that allowing FlyerTalkers the the use of images in theose areas has added no extra burden to their load.

I suspect that the actual experience of those who have dealt with images on FlyerTalk ought to carry at least as much weight as the suppositions of those who have not done so.
