I would also like to second a fantastic job on zpSkeleton. I love the fact that it supports mobile formats.

I have found one issue I would like to bring to your attention.
After installing the theme the "download" function showed on web and mobile. After checking the Options > Theme > Download Button, it showed DISABLE. I enabled it and it still showed on image pages. Only after DISABLING it again did it remove the download button from images page. Looks like your default status is not working.
