Add Unique Icons Or Image To "membership Type"

I was wondering if there is an easy way to add unique icons or image to beginning or each "Membership Type" on the signup.php page.
Each membership is unique and I would like to have a unique image to differentiate each one.
Since this is all pulled from from a database my only guess would be to add and image to the database and have that pulled in.
Just wondering if there was an easier way, since I'm not the best programmer.

Thanks.

You shouldn't put it into database.
I would recommend you to put
<img src='.......some/full/url/to_image.gif'>
into product description to insert image into product description.

Thank you Alex, that is much easier than I thought it was going to be.

Thanks
