If you just seeing little squares with x's in them its probably your browser. I had that problem the other day on Internet explorer. I couldn't see any of my OWN pictures or anybody else's.
A friend that works on pc's came over and changed my browsers. One computer is on Firefox now, and the other is on Google Chrome. (to see which one I like better). Their both great and solved the problem.
He said that Microsoft, aol and a couple others are very slow to update and that affects your viewing.
I know nothing about pc's, but changing the browser fixed the problem
