Welcome to my manipulation tutorial. Where you will be learning how to turn this,
Now open up gimp 2 and let's begin.
1st we need our image on which to manipulate. So you need to open up the folder containing your image then simply drag-and-drop your image or you could simply click on file on the top bar then open to select your image. It may take a little bit to load depending on the size.
Now that the image is loaded in we don't need all of it so let's select the crop tool.
Then click and drag over the area you wish to keep. Then release and you can adjust the size by clicking and dragging the boxes that appear near the edges. Then simply click in the middle when you're ready to crop.
Then right-click on the image in the layers menu and scroll down to Add A
