Cropping images

To crop an image:

Go the left-hand side of the screen and go to this icon (or you could press Ctrl C)

 Choose whatever size you want (you don't have to, you could do it freely!)

 Go over the area you want to keep...

The darkened area is what will be cropped 

When you're ready, press the green tick just above the image

 And your image is cropped!
