To me this looks like a block-level element nested in a block-level
element. This produces linebreaks before and after the IMG, and the
IMG is centered (in MSIE only in Standards mode).

But what should happen with the background property of an inline
element when it has a block-level child? Should this background also
be applied to the block-level child?

See this example

<p style="border: thin solid; margin-top: 2em;">bla <em
style="background: yellow;">bla <img style="border: thin solid;
display: block; margin: auto;" src="foo" alt="bar" width="100"
height="100"> bla</em> bla.</p>

Mozilla and Opera leave the background transparent for the IMG, while
MSIE colors it.

Isn't that what we have the 'Q' element for?

Isn't that what we have the 'inline-block' display value for?
