Hello.
Can you tell me how I can use pop-up menu for images? I have 4 options in the pop-up and 4 images for each option. Each option corresponds to diferetens filters. The 4 images are open in the program, I need to work with them to add 4 types of filters and to see the 4 images to each item on the pop-up.
Thank you.

You cannot attach a pop-up menu uicontrol to an image. You can, however, create a context menu and assign it to the image's UIContextMenu property.
More common would be to use a uicontrol that was near the image. The Callback property of the uicontrol('Style','popup') would get() the Value property of the control and then would switch() on the value calling the appropriate routine
switch get(hObject, 'Value')
case 1: apply_filter_1();
case 2: apply_filter_2();
end
