Can not see images in tickets

Can not see images in tickets

 Since we upgraded to version 7.5, build 7507, we can't see any images that people embed into the email they send us that generates a ticket. Also if they images in their email signatures, we can't see them either. If we right click and show picture, nothing happens.

Can anyone tell me how to fix this.  I have been through the Admin and can't find anything relevant.

Thanks
