How come I can longer post pictures in a thread?
 

I use to be able to post pictures from my computer to the threads. I know how it is done but when I try it won't let me. When I click on the "tree" above it opens a window that is all white and white back ground and I can "browse" and then the link is in the right place then when I click to "upload" but nothing happens what so ever. What's the problem? I appreciate any help. Thank you.
