Joining 2 images

[Mark Smith]

In fact it is easy:

if you want to join two images, "img1.jpg" and 'img2.jpg" it would  
look like this:

get shell("convert img1.jpg img2.jpg +append result.jpg")

As far as I can tell, magick is not installed on on-rev - I'm not  
sure how you'd go about installing it, as we don't seem to get shell  
access. Perhaps a call to on-rev support?

Best,

Mark
