You must use some more complex solution for it. When you want to show a picture you need some windows with complex code to load the picture. One problem is ofcourse getting the picture data, so you must provide some path where the code finds and loads the picture.
You also need to create some complex code with a
background thread for doing it, because it may last a moment or fail which you may present some spinner, animation or load message.
tip: the function
PostThreadMessage is sometimes useful when you message you main UI.
