How?
I use photobucket.com as a photo hosting site. Go there and sign up. Follow thier directions to upload your photos. You will then see three boxes below each photo. You want the one that says "tag" and begins with "a href". Click in that box and go to edit>copy. Then go to your account>general info>comments. Click in there where you want the photo to go and go to edit>paste
Hope this helps!
