// TIFF - PSD - PSB Files with Alpha or Spot Channels to Collection.jsx

#target bridge
if (BridgeTalk.appName == "bridge") {
    alphaFiles = MenuElement.create("command", "Add TIFF - PSD - PSB Files with Alpha or Spot Channels to Collection", "at the end of Tools");
}
alphaFiles.onSelect = function () {
    var fileList = Folder(app.document.presentationPath).getFiles(/\.(tif|tiff|psd|psb)$/i);
    withAlphas = new Array();
    for (var x in fileList) {
        var file = fileList[x];
        file.open("r");
        file.encoding = 'BINARY';
        var dat = file.read();

          I believe that the following script was from SuperMerlin, it is only for layered TIFF files. I am not sure how hard it would be to extend to PSD/PSB or to look for alpha channels.
