Hello Lukas,
One simple way to do this is to display images the way you normally would using the Read JPEG File.vi and the Draw Flattened Pixmap.vi. Then for the file path input, have different file paths in each case of a case structure. Then, when you select each case you select the file path and display the corresponding image. There are many different ways to do this in LabVIEW. This is just one way. I hope it helps!
Best Regards,
