Start with the browser example that comes with IMAQ. This shows you how to set up the browser and fill it with images. I assume you have an array of images that you are going to put in the browser. When the user selects an image in the browser, you can use IMAQ Browser Focus to get the index of the currently selected image. Use the index to select the image to display from your array of images, and display the image in a separate window.
