JPG Compression option in PowerPoint Export

Unlike everything I can find on the web I actually want PowerPoint to export higher quality/larger JPG images. I am using PowerPoint 2002 and can't seem to find a way to tell it to not compress the JPG image upon doing the "Save As" function. Most graphics packages have a "JPEG Options" button or the like that you can control this with but I am at a loss when trying to perform this from within PowerPoint.

Any help would be greatly appreciated.
