An alternative to consider might be pim's propsave xtra, if you only
need to grab the externalbitmap to grab it's image to stuff into a
texture. Who knows what kind of stuff goes on when you set the
.filename, maybe much more memory is used to parse say your jpg file, or
whatever file.. If you've got room to spare on your distribution
medium, and am worried about runtime memory usage, propsave might be the
way to go.
