Photoshop script that exports to PNG all layers and groups whose names end with ".png".
#target photoshop
// $.level = 2;
* Script by Tomek Cejner (tomek (at) japko dot info)
* based on work of Damien van Holten:
* My version adds support of nested layer groups,
* and exports single layers in addition to groups.
function main(){
if(!documents.length) return;
var doc = activeDocument;
var oldPath = activeDocument.path;
var outFolder = new Folder(oldPath + "/out");
if (!outFolder.exists) {
function scanLayerSets(el) {
// find layer groups
for(var a=0;a<el.layerSets.length;a++){
var lname = el.layerSets[a].name;
if (lname.substr(-4) == ".png") {
saveLayer(el.layers.getByName(lname), lname, oldPath, true);
} else {
// recursive
// find plain layers in current group whose names end with .png
for(var j=0; j<el.artLayers.length; j++) {
var name = el.artLayers[j].name;

Hi Tom,

It tried this script but it crashes photoshop and creates an empty out folder. Any chance you can have a look at it when you're would be really helpful.

@jaysuthar Script works fine (CS6) just make sure you label your layers with a .png ending:
e.g. "Home.png" "banner.png" or it will ignore it.
