How do I install an avatar from Iconator in Google Talk?
Once you have found your new avatar click on "Click here to download this Avatar". In the File Download box, click "Save" and save it to a place you can find again (such as your desktop).
Open the Google Talk buddy list and click on the picture to the right of
your name near the top of the buddy list window. If you do not see the
picture selector, upgrade to the
newest version of Google Talk.
Click on "More pictures..." at the bottom of the icon selector, navigate
to where you saved your avatar, select the avatar, and click "Open".
Your avatar is now installed. Hover your mouse over your name to see it
full size.
If you are still having problems, visit Google's
help section.
