Adobe Photoshop CS4 comes with a script that exports layers to files, but it adds layer numbers to the file names by default. After lots of manual renaming I decided to add an option to suppress the layer numbers.
You can download the modified Export Layers To Files script from here. Unzip the file and overwrite the original one in Photoshop CS4’s Presets/Scripts folder (to try it, run it from Photoshop’s File/Scripts/Browse menu ).
The script was originally written by Naoki Hada and Tom Ruark, Copyright 2007. Adobe Systems, Incorporated.
