I think you're both right on this one...
The way I understand it is all bitmaps except JPEGs are stored in a
PowerPoint file using PNG compression, which is lossless but not as compact
as JPEG compression. Inserted JPEGs maintain JPEG compression and therefore
can be much more effective in reducing presentation size if a happy medium
can be found between image quality and size.
But at the same time often the user inserts pictures that are unnecessarily
large and here can be the root of much excessive file size. Bill's links
are well worth investigating.
