This isn't really a big deal, but in mail whenever I write an email, or recieve an email a little photo I took the day I bought the imac (inbuilt camera) appears. It involves me, the g/f, alchohol, and little clothing.

I'd prefer it wasn't there, but I'm sure I've deleated the photo so I'm confused. I'm not totally 100% on osx yet so I'm not sure where it saves things. How do i get rid of the photo, (either from the computer or disable the image in mail?)?
