print gallery

[mvlcek]

It seems you're using the i18n Gallery plugin with prettyphoto enabled. Might be handy to add this info to the topic..

I don't have a direct (tested) answer, but googling "prettyphoto print" gives you many links to possible solutions. like:

You can create a second page, where you set the thumbnail size to a large number without crop and use a template without header and navigation. Maybe some additional styling of the big "thumbnails" with CSS (like img { width: 100%; }) and you get a page, where all images are displayed in a normal size, which should be great for printing.
