They certainly can, but they are basically just acting as a wrapper,
which has always seemed somewhat pointless to me.
People sometimes send me a JPEG inside a PDF, for what reason I wot not.
I think it's because these people don't know that you can open a JPEG in
some software; they don't have GIMP, for example, so they believe that a
PDF is the *only* shareable format, the same way as they believe Word is
the only format for text.

They may be unwilling or under contract not to share the full-res or
vector versions with third parties (I have had this problem when taking
over a contract from a designer unwilling to let me have the vector
graphics, only bitmaps; I had to get their client to instruct them).
