Looking for software to automate the process of creating 4 photo
montages.  Currently we use iphoto plus to create these montages once
we have captured images in a series of digital photos and placed them
in a photo file.  To actually create a montage we must.  Step 1. open
2 photos and stitch them together, resize them to the proper size and
rename/save (ex abc.jpg).  Step 2. open 2 more photos and stitch them
together, resize them to the proper size and rename/save (ex efg.jpg).
 Step 3 open image abc.jpg and efg.jpg stitch them together and
rename/save.  We do this process many,many, many, times each day.  We
are looking for software that will allow us to define a montage
template and automate the creation of these montages.

this may or may not work for ya!!!

I can't tell from your question how much individual input is in the
stitching together. If, for example, you're removing elements from one
picture and then inserting them in another, it's very hard to automate
the extraction process (though there are pieces of software that can
help). If, on the other hand, you're just creating a single picture
made up of four smaller pictures tiled together, then it would be
relatively straightforward to write a Photoshop action, droplet or
batch process to do this, particularly if the smaller pictures are
always the same size. As an example, I currently use a Photoshop
action to combine pairs of photos into stereo pictures. Photoshop is,
of course, an expensive program, so this is a bit of a sledgehammer to
crack a nut.
