Merging Thousands of Images

[tetrakarbon]

Hi guys! I'm creating a large map from the thousands of small, 256x256 pixel maps from google maps. I have already written a script that downloaded all the images, and saved them with a name indicating where they ought to be on the map (say, 1-1.png is top, left hand corner).

Anyway, I have to now piece all of these images together. There are about 1,800 images, so doing this by hand is a real pain (I actually have already done about 1/8th of the work, and it took 1.5 hours so far). So here's my question: is there a way in photoshop to automate this.

I know about droplets and batch things, etc. But I don't know how to make 'merge two images, with the second directly placed directly below the first in the new image.' If I knew how to do this, I could create ~60 columns with everything lined up.

Any suggestions guys? Without an alternative, I'm afraid I might have to give up Thanks!

That's quite an undertaking tetrakarbon! I think completing an eighth of the project in an hour and a half is pretty quick. Hey the whole thing would just take you 12 hours. That's not a disproportionate amount of time for such a major project, it seems to me.

I tried to figure out some way to help and feel sure someone more skilled than I could write a script to do what you want. My abilities are more limited so I tried to figure out actions using Layer > Align... capacities but came up empty.

Good Luck! It's a fascinating project.
