I'm testing out Piwigo, because I would like to move away from Gallery 1.  It hasn't been updated in years.  So I copied by photos from Gallery 1 into Piwigo/galleries, removed all of Gallery 1 files leaving just the pics, made thumbnails and did the sync thing.  Worked great, I have Categories with pics in them.  Only problem is when clicking on a thumbnail it takes me to the 2592*1944 photo.  Is there a way to click on thumbnail->web sized photo -> full size photo.

Piwigo 2.1.3
