John Waltons link to resizing photos
I have Olympus camedia master came with my camera and it has re size button I always resize mine to 800 x600 they are fine when uploaded to forum. Also I have paint shop pro 6 which also has a re size button, I thought most pic programs had one. It is best to resize before you upload pic because I don't think their is much you can do when is up their. But I could be wrong
Just found this site which will resize your pics on your PC just browse your hard drive for the pic and then follow instructions not tried it myself.
