Alright, if I where you, first I would save the picture to the desktop. If it's a screenshot,
open an art program and just paste it there. Modify it, and save it as a jpg file to the desktop
just to be safe. Go to tinypic.com (Does not need you to sign up) and click near the
upload spot Browse... your files will come up, so then go to desktop, click on the
picture you want, and click okay. The picture will be uploaded and then there will be
a thing you must type to the site knows it's not spam bot. There will be multiple codes,
pick the one that says For Forums and Message Boards. Copy the code, and then go to
your profile. Click the place where you edit your profile and paste the code into it, than
add any text you want if you desire to. Save the changes and your done!
Hope this helped.
