Here you go.Sorry took longer than I expected
For the play widget put the name of play image in status "0" and stop image in "1".For the "next" and "previous" put the name of image in the textbox next to value "0".
You would also need to update the id of the play/stop widget in next & previous widget.In the advanced settings of these two find the last line here replace the id13 with that of play/stop.
Set the size of widgets according to your preference and images.The images go in the usual queen beecon directory.
Enjoy.
Edit:
Added beecon to play/pause instead of play/stop

Edit 2:
Removed attachments and posted updated ones later on
