Well, you can have a function "load_image" which loads the image using
platform specific code. The returned datatype could be OS specific
too. I don't know if people in general ever would manually load
bitmaps (to use that as an example) under PalmOS.

Possibly but I'm not sure. Therein lies the problem. Images are loaded
into a struct which has no "data" pointer. The data is actually in the
struct but there's no variable to access it. It's hard to know how
this data is actually stored. It was a long time ago now, so I don't
even remember if you can load bitmaps from data files in a reasonable
fashion.
