I kept seeing references in Blogger to BloggerBot and Hello. When I followed the links, it took me to a page about Picasa. Picasa is some kind of picture editor/manager that google has bought. I have enough of those hanging around already. What I was looking for is just the "bot" to let me upload/host pictures on Blogger. Today, I ran across this link. Eureka! Skim over that page and go on to the Download link. You'll have to register and then Hello will download. Here's what Hello's window looks like:
You can pretty much run your blog from here. You can "Post a Picture," "Post Text Only," and "Edit a Post." I've never seen this last screen anywhere else. It pretty much lets you edit your blogs inline.
Notice that the images are hosted at blogger.com so you don't have to provide your own web space for images.
There's another subtlety that was hard to find. If you have Hello running and restart your browser, you'll get a new icon on your browser's "Standard Bar" toolbar entitled "Share in Hello." Click on that and you can send a screen shot of the current web page to Hello and then on to your blog.
