Yet another feature of WordPress that really doesn't work well is the Media Library. The problem is when you have a great many images, it really bogs down and becomes very difficult to find anything. To make it run faster, set the thumbnail size to 200x200, and use the Regenerate Thumbnails plugin to do what it says. This will result in true thumbnails that will load almost as fast as you can scroll.

As I said earlier, zero-out all the other image sizes, and add the code I supplied to stop the insanity of WordPress image handling.
