Hello,
As I figured out, Chrome do not ignore empty src, but loading currently viewed file into it. I had statistics counting error because of this "feature".
Create file.php with this code...
<?
$fp = fopen("log", "a+");
fwrite($fp, time()."\");
fclose($fp);
?>
<h1>Here is my page...</h1>
<img src="" />
<img src="" />
..and try loading in Firefox and Chrome. On Chrome one visit to file.php will generate 3 lines in log instead of one. But everything is ok in FF, IE.
Is it bug or feature? My opinion - bug.
Hope it will help anybody!
