I was running 1.4.16 and had some issues so upgraded to 1.4.18 all went fine but before and after upgrade only 1 album was displaying out of 10. Photos are in there you just have to dig to see them where before the hack/exploit albums displayed on main page see site and look at what I mean http://www.dothansoftball.com/photos
In the cpg config check your "Number of columns on thumbnail page" and "Number of rows on thumbnail page"
the link is pointing to a 1.4.16 gallery without categories and albums ???
