Remember to tap the photos on each step to see the entire photo :) This will make a printscreen into a jpeg file format or any of your choice, instead of the default - png. Jpeg can be used in emails.
Find a screen on your computer that you want to capture an image of, and press this button - which should read either "prt sc" or "prt scr".
This is the screen i chose.
Press start>paint OR type in the search box 'paint' And open the Paint application.
Once opened press ctrl+v to paste the printscreen to the blank paint canvas. Then press file>save as - then choose a file format :) Jpeg can be used in emails, most websites and transferred to a phone
Save it in your chosen library - this is where you will find the picture if u want to use it.
This is the picture saved in jpeg format.
