Maybe this is what you want:
view layout [image (bay-peg: load %bay.jpg) 500x800]
This loads it once so that it can be used again
view layout [image bay-peg 100x100]
And the image can be loaded from the internet via
bay-peg: load http://www.rebol.com/view/bay.jpg
view layout [image bay-peg 500x423]
and the better version might be to use the REBOL caching capability
bay-peg: load-thru/binary http://www.rebol.com/view/bay.jpg
(Strangely the load and load-thru are different in that load-thru
needs the binary refinement otherwise you get a less-than-satisfactory
result.)
Then after you have retrieved it and stored in your public cache,
which you will be asked to agree to per the sandbox model,
REBOL will use the cached version... so you can access it
without being connected to the internet
