OK so you have lots of pics in your PC's "My Pictures" file, right?
Google photobucket.com & register yourself there.
You go to "upload" & select the brouse button, then select your My pictures & click one the pic you want. Before clicking, you can select the size you want the upload to be.
I forget what the avatar size is, but it's likely the smallest.
Once you get it to work, hover the mouse pointer over the pic & click on the image code.
Then click just to the right of the code area, then right click that & hit copy. Now on another tab, pull up the website you want & go to "user CP"
Uhh, just remembered that most avatar uploads can be broused & uploaded directly from your PC, without photobucket.
But then P=bucket is good for posting rigpics & different junk from the interwebs.
Ask her if she remembers the folks from Clover, who were from Philly originally. We had my 16 year old son with us. Bald guy (by choice, not permanently), cute petite brunette wife, & son with glasses.
