To add your own image as an AIM picture icon, first select a photo from your computer's hard drive or other picture storage device and edit the photo to fit AIM picture icon specifications. You will need a photo editor or graphic application for this step.
Each AIM picture icon must be no larger than 50 x 50 pixels (px).

Add Your AIM Picture in Expressions
After you have edited your AIM picture icon, click the "Edit" tab at the top of your AIM Buddy List, then select "Expressions."
Browse for Your AIM Picture
Next, the AIM Expressions panel will open. Click the "Browse" link (highlighted above) to search for your edited AIM picture icon on your computer.
Next, locate your AIM picture icon on your computer, then click "Open" to continue.
Next, a dialogue window will appear in AIM asking you to ensure you have the rights to the AIM picture you wish to use as your icon. If you are the sole owner of the AIM picture icon on your computer and have all the rights to use such photo, click "Ok" to continue.
Congratulations! Once your AIM picture icon appears in the box, as highlighted above, your AIM picture is activated. Now, every time you send an IM, your AIM picture icon will appear on your IM window.
