Here's an ImageAppend() function for you. Pass it two image paths, and the
3rd Boolean flag is TRUE (default) to stack images on top of each other, or
FALSE to have them side by side. It returns an image object which you can
save, or write to the browser with <cfimage action="writetobrowser">.

ImageNew() to create a new blank image. ImageRead() and ImagePaste() to
paste first image, then another ImageNew() and ImagePaste() setting the x
and y so that it is where you want it relative to first image. Or just take
all of that and make a ImageAppend() function that dos it for you.

Subject: CFIMAGE- stacking images
Hello all,
I keep trying to find ways to use CFIMAGE but almost every time am forced to
use another tool...
Is there any way to append images? IE I have one image, a photo, that I
want to append a polaroid-like bottom to. It seems this is outside the
functionality of the CFIMAGE tag. Or am I missing something?
