I would like to put an image on the screen, and select two points with the mouse in a GUI window. Is it possible? Moreover the image size is very big - cannot fit into the screen - so rescaling or scrolling is needed.

Import the image with imread
Display it with image, imagesc or imshow. These commands scale the image to the available space already.
If you want a scrolling instead, https://www.mathworks.com/help/images/ref/imscrollpanel.html imscrollpanel would help. Further solutions can be found in the FileExchange: https://www.mathworks.com/matlabcentral/fileexchange/?utf8=%E2%9C%93&term=image+scroll
Use ginput to select points
