Path References in MikTeX

[Geoff]

Hi, I have eps files, Bibtex files, and tex files (for importing) stored in
one main directory (with subdirectories too). I would like to use the
contents of these folders from any directory I make a tex file in, however,
MikTeX doesn't search through the directories for the correct information.
Is there a way I can reference latex material in a different directory other
than the one I happen to be typing in at the time.

i.e. If my directory structure is

c:\Documents\ClassA\Assignment1\Images

and I'm making a document in the directory

c:\Documents\ClassA\

and reference some material in the Images directory, MiTeX will not search
through

...\Assignment1\Images

How can I direct MikTeX to the files in the Images directory??

Thanks for your help,

Geoff
