Before you fetch the collection put up the progress bar. When the collection is done and you are rendering the images to the DOM add listeners to the image load events. When all the images have successfully loaded remove the progress bar.

You will want to make sure you are also listening for load failures incase an image doesn't load since the progress bar would never get removed in that case.
