(not by me).

If you don't wish to use regex (or any non-standard PHP components), a reasonable solution using the built-in DOMDocument class would be as follows:

<?php
    $doc = new DOMDocument();
    $doc->loadHTML('<img src="http://example.com/img/image.jpg" ... />');
    $imageTags = $doc->getElementsByTagName('img');

    foreach($imageTags as $tag) {
        echo $tag->getAttribute('src');
    }
?>

You can use regular expressions to find the image names. This regular expression should be fine: src=\"threads_image\/([^"]+). You can use it like so:

preg_match_all('/<img src=\"threads_image\/([^"]+)/', $html , $matches);

$matches[1] is now a list of the image names.

    array (size=3)

      1 => string '<img src="threads_image/2rU4V9cbdefa8e38d5457c8b1fc7ccb77c9dc30YQJUI9N.gif' (length=74)
      2 => string '<img src="threads_image/2rU4V89e0e28ad1aab7c870d0df6380087ed378IGAN8BX.jpg' (length=74)

    array (size=3)
      0 => string '2rU4Va7c05b3f200c8cb893126fc7622b63f477ORZWM38.png' (length=50)
      1 => string '2rU4V9cbdefa8e38d5457c8b1fc7ccb77c9dc30YQJUI9N.gif' (length=50)
      2 => string '2rU4V89e0e28ad1aab7c870d0df6380087ed378IGAN8BX.jpg' (length=50)

Please note that this only works if all the images share the directory threads_image.
