SUMMARY

LINK.EXE and DUMPBIN.EXE (from Visual C++ 32-bit edition) can be used to dump the portable executable (PE) header of an executable file. Below is a fragment of a dump: 
   7300 address of entry point
   7000 base of code
   B000 base of data

        ----- new -----

   10000 image base
The "image base" value of 10000 is the address where the program begins in memory. The value associated with "base of code," "base of data," and "address of entry point" are all offsets from the image base.
