I am searching for a free script in ASP.NET(C# o VB.NET) and Ajax form image gallery, can you help me?
I've used Gallery Server Pro, if you use webmatrix you can find it in the "web gallery" it's easy to install.
Have a look at this one.
Might be easier to use, no database, it uses the folder structure of your images.
One thing, it's not free but it's license is fairly cheap.
