Why doesn't an Image resize in a Column or Grid

Consider the following With[{img = ExampleData[{"TestImage", "Lena"}]}, Column[{ImageResize[img, 400]}, ItemSize -> {30, 30}, Frame -> All]] The result is this: Why is the image, by default, this small size within its bounding area? (The same issue is also true for Grid, but seemingly not for GraphicsGrid.) The actual size of the image is In[3]:= ImageDimensions[ExampleData[{"TestImage", "Lena"}]] Out[3]= {512, 512} I have tried various options settings for Column and Grid but to no avail.

Try these two solutions: With[{img = ExampleData[{"TestImage", "Lena"}]}, Column[{Image[img, ImageSize -> Full]}, ItemSize -> {30, 30}, Frame -> All]] With[{img = ExampleData[{"TestImage", "Lena"}]}, Column[{img}, ItemSize -> {30, 30}, Frame -> All, BaseStyle -> ImageSizeMultipliers -> 1]]

Try these two solutions:

With[{img = ExampleData[{"TestImage", "Lena"}]}, 
 Column[{Image[img, ImageSize -> Full]}, ItemSize -> {30, 30}, 
  Frame -> All]]

With[{img = ExampleData[{"TestImage", "Lena"}]}, 
 Column[{img}, ItemSize -> {30, 30}, Frame -> All, 
  BaseStyle -> ImageSizeMultipliers -> 1]]

If you click on the image and set Magnification to 100%, the image is displayed full size. Puzzle is where can you programmatically set Magnification to 100%? Or why should you have to set it?
