PhotoToTypePad has been released for public beta. I've been testing it for the past couple weeks and Jonathon has incorporated pretty much every feature request and comment I made. It works perfectly for me, I typically create a new gallery, toss some photos in it, rename the titles on the images, then just export to Typepad as a new gallery.
About the only downside I've found so far is the resolution limits at Typepad, which seem to force images whatever max width and height is in your settings (typically 500-640px). Also, I have no idea how much the final version of PhotoToTypepad will cost, hopefully it'll be $5-10.
