I have a few questions related to images in gracenote API.
Let's take this image for example: <http://akamai-b.cdn.cddbp.net/cds/2.0/image/5899/C629/E091/E3A2_medium_front.jpg>

After trying to manipulate a bit the image name, i found that i could get another format for the same image: small.
Is there somewhere in gracenote documentation where i can get list of possible image formats ?

Another thing that i noticed in image name is "front".
Does that mean that there are other images for the same content that we can get ?

Thanks to anyone who can help me about that.
