I used ImageShack. After I uploaded the photo, it gave me a choice of three or four HTML strings to use (a couple were specifically designed for forum usage). I think two of them were direct to the full size image (that's the first two I tried) then the third was to a thumbnail, they actually suggested that one as it cuts down on bandwitdth used on ImageShack. I wanted to try the different methods and see how they worked out.
Nice little service ImageShack now I know I can post pictures from my hard drive onto there, then onto any forum.
