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.
GNU Trisquel 7.0 with Gnome Version 3.8.4running bash
The task is to understand how it is creating the additional files, what are they? Has anybody encountered them before?
I also want to understand if my image is created properly. Are the headers correct, offset etc
--- Post updated at 03:26 PM ---
I now have tried, seem to work. Would this be ok, or do aybody have better suggestions?

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 $?
