The fastest way to upload pictures onto this site is to use ImageShack. I personally use them for all my crazy pics.
Go to
http://www.imageshack.us/index.php and click browse, find the pic you want on your PC, click upload, then the site will present you several options. One of them is for it to copy the image onto your PC's clipboard (as if you had hit copy) so that it is viewable on forums. It will then put in all the correct coding with [IMG] so you don't need to push the IMG button on this site, it does it all for you. You just hit paste. Done.
