The closest I have seen would be something from the imagemagick package,
probably composite.
quote from the man page:
"To composite an image of a cockatoo with a perch starting at location
(100,150), use:
composite -geometry +100+150 cockatoo.miff
perch.ras composite.miff"
I think you would need to make a nominal blank image the size of the
finished product, then produce a script that called composite 47k times,
taking the geometry parameters from the file name of the image to be
added.
errr i would experiment with a smaller dataset LOL
