Reading specific height and width from an image

[Reapism]

My objective is to read an exact part of a .PNG image I have in my resources and store it in a variable.

For example. this is the image I'm reading from.



There are 16 different positions there, and I want to read each one and store it as an image.

Dim charWalkLeft, charWalkRight etc.

So whenever an event of moving right or left happens I can just make the picturebox image = to that variable.

If clarification is needed let me know.
