OK, but what is the problem? Throw away the other 3 if you don't need them. Or do you want to autmate the process? If so, it would be nice to know your OS, your shell, ... you now the drill. Supposing you can use Korn shell and your system has the standard features how about this:

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

if ! [ -f "${fIn}.${chExt}" ; then
     print -u2 "Cannot find file ${fIn}.${chExt}."
     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 hope this helps.
