>Check out irfanfiew. It allows batch conversion, under Advanced Options of batch conversion there is a convert to greyscale option. Since each file is only 2K-3K, making a smaller file size won't make any difference with regard to how much disk space will be used (because of cluster sizes on hard drive). However, irfanview does allow you to convert the JPG to another file format during the conversion, so you can experiment with that.
