<blockquote>Apparently you can already do it.

Just do it as if you were uploading a file from your computer, but when the file browser pops up, rather than clicking a file, just paste the url into the text field.

It hang for a few seconds, but it works! And it wont just link through the url, it actually uploads it.</blockquote>

The PressThis editor works differently than the full editor. Don't know WHY, but it does (and actually ... it's an iffy tool in general. I've had it bomb out on me a lot). My guess would be that the code in Press This that can grab all that page information can also scrape the content and upload images, while the full editor, not being cognizant of any other pages, cannot. AND I would speculate that the speed of the full editor would drop (i.e. it'd get real slow) if we tried that.
