Joining 2 images

[Sarah Reichelt]

Hi all you graphics gurus out there,

I have 2 images, each 40 x 40 pixels.
I want to join then side by side to end up with an image 80 x 40.
Since this is for use in On-Rev, it has to work in script only, no
stack or image objects can be used.

I am a complete noob when it come to graphics, but I know there are
people here who are experts, so if anyone has any suggestions, I would
be most grateful.

Thanks,
Sarah
