Hi Jason, Ryan,

Rebol was designed to be run when imbedded into other data,
e.g. you can run a script directly from an email, without
having to clean it first.
So, you can 'do %image.png if the script itself is stored in
normal ASCII within the binary data, but it Won't work the way
Ryan suggested, the way to go is, embed the whole script into
a block, like this
You can save this email, e.g. to %mymail.r,
and 'do %mymail.r in a REBOL session.

(IIRC, the rules are:
find newline followed be "REBOL" and a block
--> starting from REBOL unto the end is a rebol script
find newline followed by "[REBOL" and a block
--> the script ends at the closing bracket
I hope that helps,
