It fully replaces the original AspImage.dll file, so no modifications to the ASP source code is required. It is obtained simply adding the [PrgID] annotation in the main .cs file.

In the Resource folder you can find SearchProgID.vbs file which is useful to know what dll is actually installed on a given server.
