This issue sounds related to another odd behavior I encountered
recently (though this was from Mac to Mac). A user was emailing me
what he thought were very small jpeg images, but that were arriving
in my inbox as large TIFF files. I finally nailed down what he was
doing. Rather than saving an image from the web and sending the file
along as an attachment, he was right-clicking images in his browser
and choosing "Copy Image." Then he would paste into Mail.app and send.

When you do it that way, Mail.app doesn't send the image reference -
it pastes uncompressed bitmap data from the clipboard into the
message. Result - a user thinking they're sending a 19k JPG actually
ends up sending a 500k TIFF.

Seems like the PowerPoint issue is similar - an inserted file is
brought in in its existing state. But when bitmap data is pasted
from the clipboard into the document, it's up to the app to decide
how to encode/store it, and OS X apparently defaults to TIFF/LZW
for this.
