no, it's much more likely that i am...         :+)

so tell me, how would you store
3 .jpg files, a .gif file, a .png, and an .aif file,
all within a single file, readable on mac or p.c.,
such that you could retrieve them and use them?

(well, again, i'd need that .styl info as well, but let's 
concentrate on the graphic and sound formats first...)

that's all i need to do.
if it's simple, that's great.

8-bit ascii is fine, 7-bit even better...
