I'm no programmer, but over many years of Mozilla development I've spent a
lot of time hanging out in the core Moz devs IRC channels, and have been able
to comprehend quite a bit of their discussion. IIUC, Ilya is right about this
- though it seems to make no sense to an core dev outsider, image files are
just DOM objects converted on load to an internal format used by the DOM, and
grow immensely during the conversion.
