Question

When right clicking an Image in the front end, there’s the option to display at its actual size (i.e. 1:1 screen to image pixel size).

How can images be forced to be shown like this? When making a Row or Column of Images, how can they be made to display at their actual size?

^{I was comparing image resampling methods to see which one gives the best result for a sharp edges when this came up. As a workaround I ImageAssembled all the images, so I had to right-click only once to get them to display at actual size.}

Here is another method that works on version 7 at least.

img = ExampleData[{"TestImage", "Lena"}];

Row[{ Image[img, Magnification -> 1], Image[img, Magnification -> 1] }]
