Step 5Assembling the poster in Photoshop
At last, time to reap the fruits of your labour! After some math, that is.
In order for the poster to end up symmetric we need to have a nice and even amount of images so if you have, say, 317 files in your scaled images folder, just delete 17 of them so that you have 300 left.
Or, if you have for example 355, you can delete 5 and let your finished poster be 25 down and 14 across. Experiment.
Open up Photoshop and make sure you have Pixels selected in Preferences->Units&Rulers->Rulers.
Go into the File menu and click Automate->Contact Sheet.
Click the Browse button and locate your folder with the scaled images.
Let Units be set to Pixels and then try figuring out the math. In my attached example the scaled images are 200 by 200 pixels and there's 50 of them, so I figured I try out an oblong poster.
10 rows times 200 pixels is 2000 pixels so the Width should be 2000.
5 rows times 200 pixels is 1000 pixels so the Height should be 1000.
5 times 10 is 50, so all the images will fit on one page, as you can see to the right in the dialog box where it says "Page 1 of 1".
Once you get a hang of it it won't need to be so difficult.
Now just press OK and leave the computer alone for a bit.
This example took around two minutes for me to render but once you start using several hundreds of covers the wait will be longer.
I can recommend assembling smaller chunks at the time if you have more than 400 of them and then putting them all together once the composition is done.
Hopefully you'll end up with something like the enclosed example, only larger.

360 albums, 24 columns, 15 rows
that makes each album cover 80 by 80 pixels and fits perfectly!
24 x 80 being 1920 and
15 x 80 being 1200
therefore 1920 by 1200 wallpaper
