If you are talking about re-sizing digital camera prints (usually a 4:3
ratio) to standard print size (usually a 3:2) ratio a better option might be
to add blank space to the end(s) of the photo to bring it up to the 3:2
ratio. That way when you get it printed you don't lose any of the original
photo. You can do this with Irfanview 3.92 (
www.irfanview.com). It also
offers it as a batch conversion option as well so that you can convert a
large number of photos in one go.
