Help with pictures

Some days ago, with the help of a member of this forum, I put a "shop" in my forum, for the users to spend their points and have a little fun. He told me how to set up the page and everything.
He told me to do a profile field so that the pictures of the items the members bough would appear in their profiles and posts.
I came up with a problem: I cant put more than one picture in the field I want them to show up.
Can anyone tell me how to set up the profile field so that it shows more that one picture and not one.
(In the profile field is where the date joined, posts,age, not the avatar)

You could try using text zone and adding images via HTML.
