Well no, it doesn't.  Here's what it says:

	with carriage return line feed pairs treated as single line breaks.

That is,
	<new line> = CR LF | CR {not followed by LF} | LF.

Concerning line break after <img src="...>,
the specification goes on to say in the very next paragraph
	A line break occurring immediately following a start tag
	should be discarded, as should a line break occurring immediately
	before an end tag.  This applies to all HTML elements without
That is to say, any HTML user agent (browser) that treats
"<img src='foo/bar'>
and the best of luck" in any way differently from
"<img src='foo/bar'>and the best of luck"
is ***wrong***, "without exception" a line break "should be discarded"
"immediately following a start tag" such as <img...>.

Tidy is within its rights putting a line break there.
Since there are broken browsers out there, it may be unwise for Tidy
to insist on its rights, but let's be clear about where the fault lies.
