I have a 440 pixel (22x20) image. How do i create a seperate psd file from each pixel by scripting?

This should do it, the document must be open in Photoshop.

#target photoshop
function main(){
var dlg=
"dialog{text:'Script Interface',bounds:[100,100,630,270],"+
"panel1:Panel{bounds:[10,10,520,160] , text:'' ,properties:{borderStyle:'etched',su1PanelCoordinates:true},"+
"title:StaticText{bounds:[150,10,320,40] , text:'Pixel Dump' ,properties:{scrolling:undefined,multiline:undefined}},"+
"statictext1:StaticText{bounds:[10,40,300,60] , text:'Please select output folder' ,properties:{scrolling:undefined,multiline:undefined}},"+
"folder:EditText{bounds:[10,70,400,90] , text:'' ,properties:{multiline:false,noecho:false,readonly:false}},"+
"browse:Button{bounds:[410,70,501,91] , text:'Browse' },"+
"Process:Button{bounds:[10,120,190,141] , text:'Process' },"+
"button2:Button{bounds:[320,120,500,141] , text:'Cancel' },"+
"},"+
"};"
var win = new Window(dlg,'Pixel Dump');
win.panel1.folder.enabled=false;
win.panel1.browse.onClick = function() {
 outputFolder = Folder.selectDialog("Please select the output folder"); 
 if(outputFolder !=null){
  win.panel1.folder.text =  decodeURI(outputFolder.fsName); 
  }
}
if(version.substr(0,version.indexOf('.'))>9){
win.panel1.title.graphics.font = ScriptUI.newFont("Arial","BOLDITALIC",20);
g = win.graphics;
var myBrush = g.newBrush(g.BrushType.SOLID_COLOR, [1.00, 1.00, 1.00, 1]);
g.backgroundColor = myBrush;
var myPen =g.newPen (g.PenType.SOLID_COLOR, [1.00, 0.00, 0.00, 1],lineWidth=1);
}
win.panel1.Process.onClick = function(){
