I like the option of being able to view the image smaller than it's actual size because not all computers can do the extremely high resolutions and scrolling left-right and up-down is a PITA when trying to view an image.

However, to view smaller should be the option,  not have the image display small and have the option to zoom in. 

I'd like to keep the ability to view smaller, but they should reverse the default.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
