Batch Replace Smart Object With Different Image Quality and Sizes

Hi there,

I need help. I have this template that is in 1000x1000pixel and 300 dpi. I'm trying to replace the smart object inside with various JPEG that I have. These JPEG comes in large image sizes but lower than 300dpi. The issues is, when I run the script that I have, some of the pictures become really pixelated. Beforehand, I resized them to fit into the empty place in sizes that I find fit the best (8 cm x 6 cm). Some of them work okey, but then some of them just pretty bad. I'm wondering if you can help me fix the script that I have so I didn't have to resized the images before running the script, and how to make all the image fit automatically to the initial size of the image that I put the first there.

below is the script that I am using and the screenshot of my template:

#target photoshop

if (app.documents.length > 0) {

var myDocument = app.activeDocument;

var theName= myDocument.name.match(/(.*)\.[^\.]+$/)[1];

var thePath = myDocument.path;

var theLayer = myDocument.activeLayer;

// psd options;

psdOpts = new PhotoshopSaveOptions();

psdOpts.embedColorProfile = true;

psdOpts.alphaChannels = true;

psdOpts.layers = true;

psdOpts.spotColors = true;

// check if layer is smart object;

if (theLayer.kind != "LayerKind.SMARTOBJECT") {alert ("selected layer is not a smart object")}

else {

// select files;

if ($.os.search(/windows/i) != -1) {var theFiles = File.openDialog ("please select files", "*.psd;*.jpg;*.jpeg;*.tif", true)}

else {var theFiles = File.openDialog ("please select files", getFiles, true)};

if (theFiles) {

// work through the array;

for (var m = 0; m < theFiles.length; m++) {

// replace smart object;

theLayer = replaceContents (theFiles[m], theLayer);

var theNewName = theFiles[m].name.match(/(.*)\.[^\.]+$/)[1];

//Raise color picker for Back cover;

try {

app.activeDocument.activeLayer = app.activeDocument.layers[app.activeDocument.layers.length - 1];
