Hi Judy -- I took a look in your account and can see that your image library is indeed acting up. This is due the number and size of the images you have in your library. We recommend keeping all images under 1 MB, to keep things moving quickly when working in the image library.
You can delete images one by one from within your account, though we are working to make it possible for you to delete images in bulk. If you don't need the images anymore, I can have a developer wipe your library clean for a fresh start. You could add any images you need currently after that! Let me know if you think this would be helpful. We know your time is valuable!
