The process for changing your avatar/icon is pretty much the same as changing your signature.
--Go to your profile.
--Click 'Forum Profile Information.
--Here, you have two options.
1) You can upload a picture that you have saved on your own computer. Click "I will upload my own picture". Click on "Choose File", and it will bring up the images you have saved on your computer. Click on the one you want, then scroll to the bottom of your profile page and click "Change Profile".
2) You can choose a picture that you found on the internet. Copy the image url of the image on the internet, click "I have my own pic", and paste the image url into the white bar beside the "I have my own pic" button. Scroll to the bottom of your profile page and click "Change Profile".
I hope this helps.
