This will do what you want:

var srcDoc = app.activeDocument;
var imgNum = srcDoc.name.substring(7, (srcDoc.name.length)-4);
var myJpgQuality = 12

var sizeArray = [
[1400, 933, "x_paul_"],
[630,  420, "y_paul_"],
[100,  100, "z_paul_"]
]

for (var i=0; i<sizeArray.length; i++)
{
  var shrinkWidth =  sizeArray [i][0];
  var shrinkHeight = sizeArray [i][1];
  var mySaveName = sizeArray [i][2];

  var id428 = charIDToTypeID( "Dplc" );
  var desc92 = new ActionDescriptor();
  var id429 = charIDToTypeID( "null" );
  var ref27 = new ActionReference();
  var id430 = charIDToTypeID( "Dcmn" );
  var id431 = charIDToTypeID( "Ordn" );
  var id432 = charIDToTypeID( "Frst" );
  ref27.putEnumerated( id430, id431, id432 );
  desc92.putReference( id429, ref27 );
  var id433 = charIDToTypeID( "Nm  " );
  desc92.putString( id433, mySaveName );
  executeAction( id428, desc92, DialogModes.NO );

  activeDocument.resizeImage(shrinkWidth, shrinkHeight, 72, ResampleMethod.BICUBIC);
  filePath = srcDoc.path + '/' + mySaveName + imgNum + '.jpg';
  var jpgFile = new File(filePath);
  jpgSaveOptions = new JPEGSaveOptions();
  jpgSaveOptions.formatOptions = FormatOptions.OPTIMIZEDBASELINE;
  jpgSaveOptions.embedColorProfile = true;
  jpgSaveOptions.matte = MatteType.NONE;
  jpgSaveOptions.quality = myJpgQuality;

  activeDocument.saveAs(jpgFile, jpgSaveOptions, true, Extension.LOWERCASE);
  app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
}

The mad old scientist of scripting! Eh. Yes, image process 1..2...3 is available for ye olde versions of PS

paulslater3,

Yup, you've got the script to work, but don't set the action to work upon closing. A bit like wanting to go into a room by closing the door first .

The best thing to do is record the action like this: Open one of the files you want the script to work on. Record an action, from the file menu pick scripts and crops.jsx from the list. This will then perform the script. STOP recording the action. Now you need only call the script from that action, or from a batch file. Incidentally, the files get saved out in the same directory as the inital image. So if your "master" file was in C:\photos\vacation then all the smaller instances will also be in C:\photos\vacation. Hope this helps.
