Photoshop Script: Mehrere Bilder auf gemeinsame Breite skalieren

Skaliert alle geöffneten Bilder im Photoshop auf einen vorgegebene gemeinsame Breite.

Beispiel: Will man mehrere unterschiedlich formatierte (breit- und hochformatige) Bilder auf einer Website platzieren und hat dazu 900 Pixel in der Breite, kann dieses Script alle Bilder auf eine gemeinsame Höhe und der gegebenen Breite skalieren.
