Well, in this the bash version. You see why it is necessary to state your surroundings?

Code:
bakunin@host $ cat myconvert.sh
#! /bin/bash
local fIn="$1"
local chExt=".png"
fIn="${fIn#${chExt}}"

if ! [ -f "${fIn}.${chExt}" ; then
     echo "Cannot find file ${fIn}.${chExt}." >&2
     exit 1
fi
if convert "$fIn.$chExt" -crop 3000x4500 +repage -format png "${fIn}--cr.${chExt}" ; then
     rm "${fIn}-cr-1.${chExt}"
     rm "${fIn}-cr-2.${chExt}"
     rm "${fIn}-cr-3.${chExt}"
     mv "${fIn}-cr-0.${chExt}" "${fIn}-cr.${chExt}"
     exit 0
fi

exit $?

I also want to understand if my image is created properly. Are the headers correct, offset etc
This is a question best asked an expert in picture processing. I have never used this (or any other picture processing) program at all.

I hope this helps.
