Localized screenshot exporter
When I worked at The Gamebakers we needed to export localized marketing screenshots.
There were 10 screenshots, in 10 languages, and 7 resolutions (for different devices)
10*10*7 = 700
At slightly under 1 minute per screenshot this took a few days when done by hand.
I created a Photoshop script that automated 90% of the pipeline, resulting in less than an hour of work to export all screenshots.
Now we only had to go trough the localisation layers in Photoshop and make sure they followed the naming convention, and then click export.
