attached images icon

When I open many of the "for sale" posts, I see a little paperclip icon and the words "attached images," but I do'nt see any pictures. The paperclip icon is not something I can click on, and I don't see a link anywhere else. Can anyont tell me why I can't see the pictures? I can see pictures on some posts.

Thanks,

Some people don't actually attach images into posts on this site. They just post links that take you to an external site where their images are stored. Is that what you mean?
