I was looking for a simple solution for professional rank badges and stumbled onto this site and figured I would share it with you. Oh and did I mention the badges are FREE! 

You can find badges, buttons, and request just about any image you want that will match with the design of your site and forum.

After clicking the link Just scroll down to the topic that says ‘The Design Zone’ and take a gander
