So, I was wondering what the code is so that I can do an overlay of my pet? If someone could give that to me, it would be much appreciated. :)

{background-image:url(url goes here);}

I believe.

It didn't work. ):

pet_image {background-image:url(http://i25.photobucket.com/albums/c97/DarksGirlTela/Lunafinished.jpg)}

Is there something else I have to do with it?

Make sure you put the # at the beginning and place it between the style tags

In total it should look like this: <style> {background-image: url(url here);} </style>

It worked now! Thank you so much!
