Still not working? I could really use this feature
It looks like it works if you browse through the "editor", and select picture 1-60 and press download this album it does work. But then you can only get the pictures on that actual page in the zip file.
Edit: Some albums seem to be able to zip, some dont. One album with 82 pictures
did zip, but an album with 500+ pictures didn't. The album that worked did have more than one page, so I guess it is not an page-related problem.
