I would like to have some help here:

I use "Scrobbler" (last.fm and libre.fm) and it doesn't have a turn on/off feature.
I've made a beecon to control it, but not the way I would like to, it's a simple on/off, text based.

I would like to see this pic:

when it's on, and when I press it, this pic in grey, for example (wich I can provide if anyone is interested).

Can anyone help me with that? My script is here:

#!/bin/sh

LINHAS=`ps aux | grep scrobbler | grep -v grep | wc -l`;

if [ $LINHAS -gt 0 ] ; then
echo "dsmetool -k /usr/bin/scrobbler" | sudo gainroot | echo "";
kill -9 `ps aux | grep scrobbler | grep -v grep | awk '{ print $1; }'`;
echo "Scrobbler off"
else
run-standalone.sh /usr/bin/scrobbler &
echo ""
echo "Scrobbler on"
fi

So it's basically: when is on, last.fm pic, when I press again, it'll turn off and the picture will be last.fm pic in grey (another pic).
It can be any size, and I would like not to see those bees, just the image!

Thanks in advance!
