ImageMagick Script to Generate Pachyderm Images 1.0

I've updated the ImageMagick shell script I use to generate the various image sizes used by Pachyderm.

The new version is a bit cleaner, and optionally takes parameters on the command line OR runs in interactive mode to determine source and destination directories.

It also provides a little more feedback now, so you know WTF is going on.

Here's a link to the script.
