Not a serious issue though it would be nice to see these stats too. Images most viewed seems to work just fine. Pages - most viewed and News - most viewed stats are stuck on zero. In the edit page section I see that the hitcounters are indicating 0 hits on both pages and news. I guess hits aren't registered at all. I can confirm from the google analytics charts that some pages have allready more than 100 hits.
I'm using zenphoto 1.3. Thanks!
