I thought of putting some pics on there, never really got around to it, may still do it. Don't worry too much about quality, as there are lots of technically bad shots, that place is all about quantity, keywords and images that are specific and generic - but don't expect to make a lot of money off low quality pics on there. For me, as for my good shots I usually am too attached to give them away like that, would be nice to get a buck or two here and there but I'd hate for my intellectual property to be used without my permission or for a use I may have an ethical concern about. Doesn't hurt to try though, just use images you intend for that purpose, don't add any meaningful photos from your personal collection. Have fun snapping.
