Wow!  

With that many pixels, you won't be viewing them at any resolution that
justifies the montage.  

I think that you could think of different approaches; 

Write a script that loads the images on the fly for viewing - just the
ones required for the locale and zoom factor that you choose.  

Use Imagemagick (or other) to resample the 500x500 images down to a
reasonable size to suit your viewing requirements - perhaps have several
images at suitable zoom-factor resolutions - and save in a suitable
compressed-image format.  

Combine the above two into a script.  I think that I have seen a Tcl/Tk
script that does something like that.  The IMG extension is pretty
powerful, and Tk can arrange the images.  You could show the low-res
overview and the user could pick the zoom area to view - etc. etc.
