How to store an image in variable via GUI and then use it later in code?

Hi all, i'm pretty new at Matlab and I'm using it as a student. I'm working on a project and I stuck at some point. The idea is that we made an algorithm that's doing it's thing, using 2 photos and filtering them etc. That works fine when you enter the name of the file in .m file, but we need to create a GUI where you have buttons to load images (have axis to show them) and after that you have to press another button to begin it's simulation/task. How can I do that? I know how to load those images as a button callback (with browse options), but how to use those loaded images later on other button callbacks? Thank you in advance! I hope i was clear enough, and hope someone can help me cuz it's kinda urgent :)

You need to pass variables among GUIs through their handles. There are plenty of QAs on this topic. Search the forum and see if you can find the answer, like
