Any image I try to link into a message using the little tree button shows up as a blank box.

Any image on any post which I click on and "view image" downloads to my hard drive instead of opening in firefox. If I click on the image and "copy image location" and paste that in my browser, that also makes it download to my hard drive. 

It never worked like this before.  Used to be able to insert an image in your post and have text between images....people said that it made it much nicer to read the thread.  

Laptop is down at the moment, so I'm only using one computer...there's a slight possibility I have something messed up in firefox on the desktop, but I don't really think so.
