How do I copy photos to the Xbox360...??

Can anybody tell me how to copy images (jpg) to the Xbox360 HDD?

I could be completely stupid and be missing the obvious, but I have tried a disk, a USB stick and a networked drive, at no point could I see an option to copy.

I'm trying to get my gamer face on my Tiger Woods PGA 2009 profile.

I don't need to tell you guys this is a life or death situation and informed responses are required post haste.

Well done in advance.
