Just a thought - Could it be possible they want to be able to zoom in close and see what kind of detail they are really getting?

If I can, I'll send them pdf's with vectors, however in practice the proofs are works-in-progress so I'll almost always send bitmap/gifs/jpegs.

I've also found that if I get colour shifts on certain objects its very often becuase the object has an RGB fill, while all the other objects have CMYK fills or vise-versa.
