Won't that just kill your bandwidth? A image converted to text is always going to be twice the size.
I'm struggling to see the point :/
EDIT: It's Base64 though innit so not twice the size. My bad. Still bigger though.
EDIT2: I suppose it might be useful for HTML emails - no need to worry about maintaining image attachments etc. Not that that's especially difficult.
