Adding cover art to blog posts

So, I've started doing a series of Where I Read posts for Heavy Metal Magazine. I'm carrying them over from another forum site I did them for, mainly for posterity, but also because I can format the posts better here, on the blog.
 
Anyway. I'm wanting to include the cover art for the respective issues with my blog posts. I know we have the art on the site for those issues. However, I can't seem to find a way to include those specific pieces of cover art with the relevant post, without basically re-uploading the artwork to the system. Is there a way I could go about doing this?
 
I'm currently using the most recent version of Mozilla Firefox on Windows Vista.

That's what I thought. I'll just stick with re-uploading, as part of the reason why I'm putting the blog posts here is because I want the maneuverability.
