Media library is show list of media but no images

Hi Guys,
I used the "New Bog Template to create a new blog in my network.
While testing I noticed the suer avatars are not showing .
I checked the media gallery and see the list and link locations are correct but the images do not show.
I noticed the links were specific to the new site so I deleted the media library list and uploaded new images.
Same thing, list and links are correct but the images do not show.

Any suggestions?
