Hey Adywan, frequent lurker, infrequent poster here...
Anyway I came across this site and thought I'd point it out to you, they have some nice hi-res shots that might be good for reference, if nothing else...

Unfortunately you do have to pay but its relatively cheap...
Just search for "Star Wars"
Also quite handy for those making DVD covers (that's how I found it)
