When .NET first came out, I start a project to:
- learn the .NET Framework
- learn C#
- fill my need of a digital photo mass-renamer
This app is free and anyone can use it. It will resize pictures for you, rotate, and help you do a mass renaming of a bunch of pictures. Feel free to nab if it you want... keep it in mind it was done right when the Framework came out (RTM v1.0) and was my first app so performance isn't ideal.
