Photoshop Script to save multiple sizes of an image. I use it for work.

zoomify.jsx

var inFolder = Folder.selectDialog("Please select folder to process");

if(inFolder !== null) {
  var fileList = inFolder.getFiles(/\.(jpg|tif|psd|)$/i);
  var outfolderName = prompt('Folder name', 'zoom');
  var outfolder = new Folder(decodeURI(inFolder) + "/" + outfolderName);

  if (!outfolder.exists) outfolder.create();

  for(var a = 0; a < fileList.length; a++) {
    if(fileList[a] instanceof File) {
      var doc = open(fileList[a]);
      var docname = fileList[a].name.replace(/\.[^\.]+$/, '');
      zoomify();
      doc.close(SaveOptions.DONOTSAVECHANGES);
    }
  }
}

function zoomify() {
  var savedRuler = app.preferences.rulerUnits;
  var w = app.activeDocument.width;
  var h = app.activeDocument.height;
  var quality = 50;

  app.preferences.rulerUnits = Units.PIXELS;
  if(w > h) app.activeDocument.resizeCanvas (w, w, AnchorPosition.MIDDLECENTER);
  if(w < h) app.activeDocument.resizeCanvas (h, h, AnchorPosition.MIDDLECENTER);
  app.activeDocument.resizeImage('2560px', undefined, undefined, ResampleMethod.BICUBICSHARPER);
  app.preferences.rulerUnits = savedRuler;

  for(var i = 4; i >= 0; i--) {
    var outfolder = new Folder(decodeURI(inFolder) + "/" + outfolderName + "/" + docname + "/TileGroup0");
    if (outfolder.exists === false) outfolder.create();
    var saveFile = new File(decodeURI(outfolder) + "/" + i + "-0-0.jpg");
    SaveJPEG(saveFile, quality);
    app.activeDocument.resizeImage('50%','50%', undefined, ResampleMethod.BICUBICSHARPER);
    quality = quality + 10;
  }
}

function SaveJPEG(saveFile, quality) {
  var exportOptionsSaveForWeb = new ExportOptionsSaveForWeb();
  exportOptionsSaveForWeb.format = SaveDocumentType.JPEG;
  exportOptionsSaveForWeb.includeProfile = false;
  exportOptionsSaveForWeb.interlaced = true;
  exportOptionsSaveForWeb.optimized = true;
  exportOptionsSaveForWeb.quality = quality;

  activeDocument.exportDocument(saveFile, ExportType.SAVEFORWEB,exportOptionsSaveForWeb);
}
