If not using IDL for the final image is an option, then you should try
montage (from Imagemagick) to tile the images. You have control over
the layout, the individual image sizes and the spacing between the
images.

Here is the man page for montage:
http://www.imagemagick.org/Usage/montage/

If all else fails, convert from the images from png to eps, include in
a tex file in the layout you want and generate a ps or pdf file.
