The next release of zenphoto will provide a custom sort that lets you sort by any field in the database. (This is available for preview in the nightly builds.) There is not exactly a field for the rating but there is a total_value field. That might be close enough.
Ok, I'll look there for setting that field...thanks
Before I switched to the nightly build I had a image.php file. See this thread : http://www.zenphoto.org/support/topic.php?id=4812
I added a hit counter. Now with the nightly build I have no hit counter and no image.php file to edit.
I do like the statistics page and I suppose this would suffice..
My main concern right now is the sorting..
