Hi
I use this service
http://www.fotos-hochladen.net/
I'm shure that this exist in English too.
I fyou want to try: Durchsuchen=select a pic, open it; Foto nicht skalieren=original size, better is 800x600; Bild hochladen= upload pic. A new screen opens with all possible links to copy. In this case "Foto für Foren". If you get stuck take the faint "Foto hochladen" in the first screen and you restart again.
Cheers Charles
