Requested feature overview description.
Display the file size of a image when making a new upload. Use the same formatting as the 'Size' field on posts.
Example: 1280x1144 (819.9 KB) -or- 1695x1831 (1.3 MB)
Why would it be useful?
1) Uploading from a direct image link does not show the image's file size in a download manager.
2) Not all browsers display file properties when downloading content anymore. As a result, users may to keep a network request analyzer open at all times or manually right-click the file after downloading and open up its properties.
Stating the image's file size during upload would provide more information to users who upload from direct links, and it would prevent additional hassle for those who download content to their device first.
