How do I remove the unwaned pics & songs from my new MP3? - new pics of myammee

My son has just got a new MP4 player Coby Christmas. When you download songs to it for some reason, the following have downloaded the photo from my team. That is a lot. I can not imagine how to remove them. This is a MP705-4G. There is no option to remove it I can find. Is it really necessary to remove the photos.
