LOL!! Just "a kind soul". I create a lot of the graphics. Not all but most of the "Welcome" etc graphics. Take a look at the group "Graphic Designs", you are welcome to download any you like and upload in the comment section of friends and groups, etc.
Debbie Jackson is the site admin and I have created many of the graphics she uses in the groups as well as her Welcome & Birthday graphics.
I like your avatar, did you create it? I have found 175x175 pixels work best for group icons.
