Answer 1

You need to make sure that the image you're trying to find on the screen isn't larger than your display resolution, as an image can't be found in a different image smaller than it.

Answer 2

locateOnScreen('image.file',region=(startXValue,startYValue,width,height),...)

If the dimensions of the image you are looking for exceeds the width and height of the area you are looking in, the method throws an error.

Make sure that the area is large enough to have your image fit inside.

To get the image dimensions on Windows: 'right-click' on the image in your folder, click 'properties' proceed to the tab 'details' there you can see what the minimum 'width' and 'height' should be.
