If I have two images coming out from two [#in], I can make a wider image 
that contains both images side to side using [#join 1], but this is not 
the only way of putting images together to form a bigger image. for 
example, it could be about alternating slices of both images. In that 
case, I'd use a [#remap_image] after the [#join 1], to shuffle things 
around a bit.

But you didn't say whether you want to do this with GEM, PDP or GF.
