Free software to quickly put multiple images on same page for printing?

My reaction to this would be to print every single one of them into a postscript file (perhaps using find and display) then psmerge them into a single file, then psnup them into 2x2 pages per page.

Failing that, I'd probably write a small Perl script to generate a latex source file that would include all the images in 2x2 format and use pdflatex on it.

EDIT: besides, convert -adjoin *.jpg output.ps might also do the trick.

I'm on a windows machine right now, but I'll be moving them to a linux machine for printing (I don't have a printer at home), so as far as I can tell I can't do that from here, may try it though.

Turns out using IrfanView's thumbnail viewer you can save multiple thumbnails as an image, and it didn't take nearly as long as I thought it would.

Thanks, and if someone has any more ideas it may be helpful in the future :).
