I don't think it is the images that are all of the problem because if I open the editor on one computer first and then open it on another within an hour or so it is super fast, which makes me think it is because the editor is in the server's cache to make it so fast. Unfortunately for what I use this for it doesn't get used every hour, so I get a lot of complaints about it being slow for the users:(. Just hoping there is a way to make it stay in cache even longer:)
