Currently running Dell Demension 8400,Intel (R4), Pentium (R) 4 CPU 3 3.00 GHZ, 2.99 GHZ, 512 MB OF RAM, Microsoft Word sp3

 My problem is trying to use a tool in word that compresses picture file sizes to reduce the overall file  size of a document. Within this program you have an option to reduce the file size of one picuture or all pictures in the document you are working with.

However I have been unable to make this tool work and subsequently I have been unable to reduce the file sizes of documents I have inserted pictures into.

Also I have been using a Kodak Easyshare program

Is there anyone out there that could please advise me on this situation or tell me where I could otain help with it?
