[Seaside] image handling (thumbnails)

[Francois Stephany]

My OSProcess call is pretty stupid actually. It's something along the line:

env := OSProcess thisOSProcess environment copy.
path := (env at: #PATH), ':/usr/local/bin/:/usr/bin/'.
env at: #PATH put: path.

pipe := (PipeableOSProcess command: command environment: env).
pipe output.
pipe closePipes.


where the command is the imagemagick command as you would use it from 
the command line.

I think SMagick does the same kind of thing but have a nice Smalltalk 
wrapper around.
