Pasting from a script centers the image

Question

Hello,
I'm new to these formus and to extendScript in particular, and I would be verry happy if someone could point out what I'm doing wrong.
I have a script that opens a image (lets call it icon), and for all the images in a folder, resizes icon to the current folder image, pastes the image on top, and saves it.
It works great except for a small problem which I can't seem to fix. When the image from the folder is smaller than the canvas ej:
Then when the image gets copied over the icon image, it's pasted centered, like this:
Which defeats the purpose of what I wanted to do, I needed it pasted in the same position as it was in the original image. As we are talking of well over 1k images, doing this by hand is a bit problematic, so I would be really thankful if someone could help me out.
Here is the script:
#target photoshop
app.bringToFront();
function main()
    var iconFile = File.openDialog ("Select the base (icon0) file", "*.png", false);
    var inputFolder= Folder.selectDialog ("Please select folder to process");
    if(inputFolder == null) return;
    var fileList = inputFolder.getFiles("*.png");
    var outFolder = Folder(inputFolder +"/Processed");
    if(!outFolder.exists) outFolder.create();      
    // Open icon file and create a new layer, making the background one invisible
    var icon = open(iconFile);   
    var artLayerRef = icon.artLayers.add()
    icon.layers[1].visible = false;
    for(var z in fileList)
        // Open icon file
        var icon = open(iconFile);
        var artLayerRef = icon.artLayers.add()
        icon.layers[1].visible = false;
        // Open 32 bit file
        var img32 = open(fileList[z]);
        var img32Name = decodeURI(fileList[z].name.replace(/\.[^\.]+$/, ''));
        // select all document
        img32.selection.selectAll();
        img32.selection.copy();
        // Copy image to the icon layer
        activeDocument = icon;
        icon.resizeImage (img32.width.value, img32.height.value);
        icon.paste();
        // Save icon with name
       var saveFile= File(outFolder + "/" + img32Name + ".png");
        Save24 (icon, saveFile);
        // Clear layer, close open image
        icon.selection.selectAll();
        icon.selection.clear();       
        img32.close();
    icon.close(SaveOptions.DONOTSAVECHANGES);
main();
function Save24(doc, saveFile)
     pngSaveOptions = new PNGSaveOptions();
     doc.saveAs(saveFile, pngSaveOptions, true, Extension.LOWERCASE);

Hy Michael,
first, thank you for taking time to reply. I apologize for how confusing the post is, I realize how hard it is to understand by code, so I'll try it with images to make it clearer.
Here is the original icon file:
// Open icon file
        var icon = open(iconFile);
        var artLayerRef = icon.artLayers.add()
        icon.layers[1].visible = false;
And now we open the first img32 file (sorry for the size, it's a bit hard to see but there is a small green hill on bottom left)
// Open 32 bit file
        var img32 = open(fileList[z]);
        var img32Name = decodeURI(fileList[z].name.replace(/\.[^\.]+$/, ''));
Then we select the img32 and copy it:
// select all document
        img32.selection.selectAll();
        img32.selection.copy();
And then we resize the icon document to fit the img32 size:
// Copy image to the icon layer
        activeDocument = icon;
        icon.resizeImage (img32.width.value, img32.height.value);
Finaly we paste on the icon the img32 content we had copied:
icon.paste();
Notice how the img32 contents get copied smack in the center? I needed to copy it in it's original position, not the center.
You can probably see the problem with working with translate, as I can't figure out the displacement the image needs. All images I need to work are different sizes and positioned in random positions in the canvas, so I can't hack it to be always bottom right or something like that, I need it in the original position.
Any tips? Your help is greatly appreciated, and frankly, the only hope I have about this whole busines right now.
Thanks again.
