Pictures

I can't figure this out. I can't post pictures anymore. When I click my "Add Image" icon, nothing happens. I took out all my pop-up blockers but it's still not fixed. I changed to another template (for some reason, when I've done this before, I've been able to add pictures.) I've cleared my cache of everything except Blogger. I've cleared that, too, and signed in all over again. I've turned off the computer, restarted.

NOTHING I DO IS ALLOWING THE PHOTOS WINDOW TO POP UP!!!! I could take this da*n computer and throw it out the window. I am so furious. This thing is part of the general conspiracy to make me feel tricked, incompetent, and stupid. Part of the world's plot to drive me crazy.
