jQuery UI Button Icons

jQuery UI Button Icons

I am trying to add button icon images on my page buttons.
  1.     <div style="font-size: .6em">
            <button id="btnSave">
                Save Address</button>
            <button id="btnLoad">
                Load Address</button>
            <button id="btnWorkflow2">
                Run Workflow</button>
        </div>






That is how I have the buttons declared. This is how I'm trying to assign the icons.
  1.             $("#btnSave, #btnLoad, #btnWorkflow2,#btnLoadAddressTypes").button({
                    icons: {
                        primary: "ui-icon-locked"
                    }
                });



The buttons look all jQueryified so that part is working. It's just not loading the images. Here is how I've got my Visual Studio Project set up:

Main Folder
"images" folder
   - jQuery UI image files attached to the theme I'm using
"Scripts" folder
   - jQueryUI and jQuery javascript libraries
"Styles"
   - jQueryUI CSS file and my own custom style
Main.aspx

Like I said, the jQuery UI functions are there and appear to be working, but the images are not loading up. Any suggestions?
