Images not showing in my new themes

Hi there,

When I upload new themes, the images are not showing anywhere? I have only worked with single site before and have never had this problem.

I am new to multi site, so it might be something really simpel I am missing and have to change? I had a someone to set up my multisite and I am not sure if he have done it right. Mayby a path problem?

Hope someone can help me

Cheers and thanks,
