or, if youre using pc like i am, press alt and print screen at the same time (print screen is most likely shortened to prt sc on your keyboard). then, open a photo editing/drawing program like paint tool sai or krita and press ctrl+v and the photo should show up. then, press the file tab, press "save as..." and save the photo (remember to save it as a jpg, jpeg, or png file!). then, if you want to, open the file and crop the photo. hope this helps!
