I have a Tomboy note relating to tiling images,  it has psuedo-code of:

from PIL import Image

wfile = open('myfile.jpg', 'wb')
x = Image.new("RGBA", (w,h), color)
for i in images:
   i.thumbnail((desiredw,desiredh), Image.ANTIALIAS)
   x1, y1 = figure-out-the-placement
   x.paste(i, (x1, y1))
x.save(wfile, "JPEG")

Note that while is seems odd the thumbail method generally produces
better results than resize; or did under whatever version I dested with.

There is an example of some working thumbnailing [but not tiling] PIL
