scatter plot atop image

Hi,

I am trying to overlap coordinates atop a picture:

a=imshow(SpecificPictureName); %Show the original image
hold on
h=scatter(SpecificX_Coordinates,SpecificY_Coordinates,'.r'),a;

However, the picture is too large to fit on my screen so matlab warns me that the image has been resized:

Warning: Image is too big to fit on screen; displaying at 67%

The problem with this is that the coordinates are in relation to the original sized image.

Is there a way to get the coordinates to correctly map onto the image?

Thanks!
