Rufe Dude, I have used a free program called photofiltre for several years now and it works great for adjusting photos for posting on forums. Just right click on the photo you've loaded and go to image size, you can adjust it and see if the size is usable in the forum.
Another thing I use is a Photobucket account-also a free program-it will let you post pictures numerous time, the attachments on line will usually only let you post it once. I have about 2 hundred photos as well as some videos on my Photobucket site.
I use soundclick for my music posts as well, it doesn't compress the songs as much as MySpace will.
Here is the link to photofiltre--
