-right-click save image as or drag & drop the image into your painting program
-resize it to be 2x2 pixels because all spritesheets are 1x1, in Paint.NET you can do this using the Resize Image function, hotkey Ctrl+R
-when resizing, use the "Next Neightbour" type which you can select. It prevents the image from blurring
-select the area on the image you want and
a) paste it onto the NPC's .gif file
b) paste it onto a new file which you will then design to be the new npc .gif file. I do this when the new sprite is too large/small or has more/less frames
-make sure the background is black in the end and you make a mask for it
This is pretty simple I'd say. Try it out. I can make an image tutorial if you still need help.
