It looks like I can add images to other parts of this page, for instance the sidebar, by uploading the images into a post that I only save as a draft, finding out the URL to the image in that post and then simply using it elsewhere in the HTML.
Posts don't have URL's 'til you publish them... (I had to know that for some reason a while back...) but I guess the images in drafts have to have URL's before / during the pasting process? I'll try it on my test blog, maybe. If you try it, hit the comments & let me know whether it flies. We may have just cracked the "external image hosting sucks" bug that plagues us here at blogspot!!
