Very long I suffer I can not repair

Very long I suffer I can not repair.
Couldn't find at a forum a solution of a problem.
Problem essence:
I establish plagiarism, I activate, I adjust, I register images, but instead of them a black box.
Interesting that that small images are also transition is, and big aren't loaded.
Earlier established a plug-in, on this cursor of a site and the same theme. All worked, and now isn't present.

looks like you have conflict with some plugin(s), try to turn it off one by one to see which one is causing the conflict
