Hi, first of all read about the series in core manual.
http://www.rebol.com/docs/docs.html
Because images are also series. If you want to draw something (not just
putting pixels; box, circle, line etc.) read "REBOL/View Draw Dialect 1.3"
part in the docs.

No it doesn't, but i did it with line:
xy: as-pair xs ys
append plot reduce [
'pen (black)
'line xy (xy + 1x1)
]

here is what you want:
img: make image! 100x50
lay: layout [image img]
putpixel: func [x y] [change skip img 100 * y + x white]
putpixel 40 20
view lay

You can of course still draw on the image created above using DRAW:
draw img [...something...]

It's easier than that:
>> img: make image! 100x100
== make image! [100x100 #{
000000000000000000000000000000000000000000000000000000000000
0000000000000000000000000000000000000000000...
>> poke img 5x5 white
== 255.255.255
>> view layout [image img]
Ie. use POKE with a pair! and a color. You can use the fourth element
of the tuple to set the alpha channel.

See the 'draw' docs...
http://www.rebol.com/docs/draw.html
That should get you started. And do ask for more help here if you have any problems.

I already get the answer, thank you.

I see that. The other replies arrived first because mine took hours to arrive! You'd
had none when I answered.
