Can others edit my Photos
Photos NOT OK to edit
I wanted to make a montage of pictures from a set of pictures my son-in-law sent me. They travel a good deal and he got into the habit of taking a photo of his shoes with an iPad everywhere.

I found a script on Adobe Photoshop - Scripts Related to Montaging - NoskeWiki
that will take a set of ordered (by number) files and make them into a montage.

Copy the text below the line and save it into a text file with a jsx extension e.g. feet.jsx.
Go to Files>Scripts>Browse and find your script.
You will be asked to locate the set of files and enter the number of columns.

NB: the files should all be in same aspect ratio and the long sides oriented the same way.

// Assembles a folder full of ordered image tiles into a single montage image
// with each tile in a separate layer. Before processing and tile translation
// occurs, you will be prompted to enter the number of columns and whether
// tiles are ordered by x or y first. If possible, I recommend you name tiles
// like so: "my_tile_x=0&y=0.jpg". Tiles *should* work as any image type, but
// I have had trouble before with .png, so you may need to convert to .jpg.
// All tiles are added to the first tile, and then saved as a PSD (with one
// tile per layer) at the end.
//
// TIPS:
// > This has been tested up to 80x80 (256x256 pixel tiles), but over 30,000
// in any dimension is not supported by all photoshop versions.
// > The final PSD won't save if > 2 GB (easily fixed by saving as a TIF)
// > Images can be different types, but certain image "modes", including
// "Indexed" color, fail (fixed by Image > Mode > RGB Color).

// Open folder selection dialog (for user to chose folder):
alert("You will be prompted for the folder containing your tiles.\n" +
"Tiles should be named like 'x=10&y=4.jpg' so they sort well, " +
"all of the identical dimension and the folder should contain " +
"no other image files.");

var folder = Folder.selectDialog();
if (!folder) {alert("Cancelled"); exit;}

// Set units and guess the number of columns using square root:
var origUnits = app.preferences.rulerUnits; // Can delete.
app.preferences.rulerUnits = Units.POINTS;
var files = folder.getFiles(/\.(jpg|jpeg|tif|tiff|bmp|png|eps)$/i);
files.sort();
var numColGuess = Math.ceil(Math.sqrt(files.length));

// Prompt the user to enter the number of columns and if x appears first:
var numCol = prompt("Found " + files.length + " images.\n" +
"How many columns are there?", numColGuess);
var numRows = Math.ceil(files.length / numCol);

var answer = prompt("Grid will be " + numCol + "x" + numRows + " tiles.\n" +
"Does x or y appear first in the filenames?", "x");
var orderedWithYFirst = (answer == "y" || answer == "Y");
if (!answer || numCol == 0 || numRows == 0) {alert("Bad values"); exit;}

// Open first file to determine dimensions:
var firstTile = app.open(File(files[0]));
var tileWidth = firstTile.width;
var tileHeight = firstTile.height;

// Resize first file to a size that will fit all tiles:
var firstLayer = firstTile.layers.length - 1; // Most likely 0.
firstTile.layers[firstLayer].name = files[0].name.slice(0,-4);
firstTile.resizeCanvas(firstTile.width * numCol,
firstTile.height * numRows,
AnchorPosition.TOPLEFT);

// Zoom to fit whole image on screen:
doMenuItemNoInteraction = function(item) {
var ref = new ActionReference();
ref.putEnumerated(app.charIDToTypeID("Mn "), app.charIDToTypeID("MnIt"), item);
var desc = new ActionDescriptor();
desc.putReference(app.charIDToTypeID("null"), ref);
executeAction(app.stringIDToTypeID("select"), desc, DialogModes.NO);
}
doMenuItemNoInteraction(app.charIDToTypeID('FtOn')); // Fit all on screen.

// For each tile: open, transfer into a new layer, and re-position:
for (var i = 1; i < files.length; i++) {
var tile = app.open(File(files));
if (tile.layers.length > 1) {
tile.flatten();
};
tile.layers[0].duplicate(firstTile, ElementPlacement.PLACEATBEGINNING);
tile.close(SaveOptions.DONOTSAVECHANGES);
var layer = firstTile.layers[0];
layer.name = files.name.slice(0,-4); // Omit the file extension.
// Determine current column and row:
var col = Math.floor(i / numRows);
var row = i - (col * numRows);
if (orderedWithYFirst) {
row = Math.floor(i / numCol);
col = i - (row * numCol);
}
// Calculate the x/y offsets and translate image:
var xOffset = (tileWidth * col) - layer.bounds[0];
var yOffset = (tileHeight * row) - layer.bounds[1];
layer.translate(xOffset, yOffset);
};

// Save as new file;
var basename = firstTile.name.match(/(.*)\.[^\.]+$/)[1];
var docPath = firstTile.path;
psdOpts = new PhotoshopSaveOptions();
psdOpts.embedColorProfile = true;
psdOpts.alphaChannels = false;
psdOpts.layers = true;
psdOpts.spotColors = true;
firstTile.saveAs((new File(docPath+'/'+basename.slice(0,-4)+"_comb.psd")),psdOpts,false);
app.preferences.rulerUnits = origUnits;

===========================================================
The result is a fairly large montage like this.
