Hi
Woodoworkery:
I tried Imgur, but they have some pretty obscene advertisement on their site.
I switched a lot of my stuff over to Imgur a while ago and have had no problems. To be honest, I don't remember seeing any ads there either. I know what can pop up on the main page before you log on, and indeed after, but that's what other people have posted there and not imgur themselves. Luckily the turnover is pretty fast so they soon disappear. I might be completely wrong, if so sorry, but I'd give it another try.
Good luck
Rich
