I think it is not a good idea to copy dependencies from one machine to another. If you want to run application on Client's machine, you've to include .NET Framework 2.0 runtime (redistributable)setup package. The setup program performs various operations like copying assemblies and files, registering assemblies in GAC, copying COM servers like MSCoree.dll and registering them in registry and many other tasks.

First you have to distribute the .net framework to all computers that the application will work. And then you have to distribute the components that you use also. For example: What component do you use to display the images?? Thats the problem.
