There are more ways to do this depending on your situation, here you will learn three ways, which i think are the best and easiest. Here we go. To start in the first method we need to use the most common method - the Prt Sc button which you can find on most computers (but you may not find it on all laptops and this one is not working in Mac) and it may have another name, but it will be similar to it.
The First Method (For Windows users)
Search for it and once you find it go at the place you want to take a screenshot (ex. the desktop) and then press on the button. After doing that open Paint (if on Windows, if on Mac you will need to use the second method) and paste the picture there. After doing that you can easily save it.
The Second Method (For Mac users)
This one is for Mac users. You need to do a 3 key combination to make it work. You can take a screenshot but pressing Command button + Shift button + Control button + 3 and then to paste the image and directly have it on internet you can use this site: www.snag.gy and paste the picture directly in there.
The Third Method (For Windows users)
This method includes using a program that you can find in Windows OS called "Snipping Tool" which you can find by going to: All Programs ---> Accessories ---> Snipping Tool. And when the program starts just click on "New" and then select your picture area. This program is good because you can edit the picture right after taking the screenshot and you can select the photo area you want to be taken.
