yep, Birdmom's got it!
You can also go to
www.photobucket.com and register for an account (its free) and you can upload photo's to there. Then there is a URL code (actually about 4 of them) that comes with them, You can then Take the bottom code that says img code and copy it and paste it to your post, it will automaticly show up then after you post your post. :)
Happy Posting!
*** This is just a little more of a complicated way to do it, but both ways work****
