Use the mouse wheel to zoom into images

I would love to be able to zoom into images using the mouse wheel, as it is standard in photoshop or other web image viewers. Wheel up for zoom in, wheel down for zoom out, and the area under the mouse pointer is where the zoom is centered. I find this behaviour very intuitive, and it would also reduce the necessary clicks and drags for zooming quite a bit.

Would you consider adding this functionality?
