The big thing for me, though, would be the ability to directly download a Jpeg again, rather than have to have only the ability to Save a web page and then extract a Jpeg. In itself, if it worked as it is supposed to the Right-left scrolling doesn't really add anything from the up-down scrolling you had before. But if you like it and it keeps up with the Joneses, fine.

And so far the description and editorial tabs really don't seem to add much. Just make for more needless clicking. Maybe get rid of one of them so the editorial tab is already on the page?
