I don't know much about ImageMagick. However, I have recently started 
using the PEAR module Image_Transform, and find that it works pretty well. 
It supports ImageMagick, gd library and NetPBM via a driver interface.

I suggest this because I see you are dropping to a shell to execute your
IM commands, which is what I was previously doing with NetPBM--a kludgy
approach which has always bugged me. The Image_Transform module does it
too, but gives you a nice abstracted interface that is the same regardless
of the underlying driver in use (the drivers are included with the package
and amount to classes that extend the main Image_Transform object).

This also enables you to switch the underlying graphics system without 
changing your code. That's a good thing because you can often expect that 
one of the three packages will be available on a given host, but rarely 
all three (and odds are, probably not the one you were hoping for).

After installing the package, I was able to do my transformations without
any extra setup (I already had NetPBM installed). I also found it easy to
hack in some extra cropping features which were not yet implemented in the
package. I think it's a beta, but what is there seems to work great.

Of course, if there is a problem with your IM install, then this probably 
won't help. I thought I would mention this package in case you or others 
found it useful. It certainly makes life a lot easier than it was!

You can find the package here:

PEAR rocks, yo!
