I’ve been using Ktools photostore since early 2004, takes a bit of work to get it the way you want but has never let me down.

I’ve changed my site to another provider recently and have been holding off doing work on my store as a new version is to be released soon, V3 I’m using now and apparently V4 has changed that much that a fresh install will be needed

From the screen shots on the Ktools forum V4 is looking like a major improvement but I’ve not researched any alternatives lately so any other suggestions?
