Isn't your site also limited on how many images can appear on a page without causing problems browsing the page?

The way you do images (i.e., just by copying and pasting straight into the editor), it might be a little slow. Most sites don't support this. It would be faster if you actually uploaded the images, as files, to the QDL server. (See Uploading Images for more info.) You don't get to control the rights that way, but performance-wise, it's better.
