load multiply image on GUI

when using GUI , I use Axes to load images, and load the first image successfully, however,when I load the second image, it becomes small than first image and overlapped on the first image. How can I remove the first image and make the rest image the same size as first one? which function should I use? Thank you very much!

Use "cla" or "cla reset" in between calls to imshow() or whatever.
