I've noticed how large images are resized to fit the browser window, which is great. On other sites they can force the browser window to stretch very wide. I also see there is no notice during image upload of a max file size. I spotted one example where the uploaded image was 2,256px × 1,496px but the display was scaled to 780px × 517px. Click the display and the full image appears. Great functionality, but it raises a big question. That image was about 880k. Does that mean every time someone loads that page, their browser d/l's an 880 k image file, or does MP automatically create a smaller, lighter weight version? If the former, then I think you need to put a limit on image upload size.
