Multiple results in regex

Hi. I have a string that has multiple references to images in it. I want to pull each reference out using regex. I've gotten to where I can pull the first instance out, but not ALL of them. I know each image source starts with 'images/'. I have this so far.... <?php $pattern = '/[\'\"](images\/[a-z0-9\/\-\_\.]+)[\'\"]/i'; preg_match ($pattern, $string, $matches); ?> // For example, returns... Array ( [0] => "images/some/location/some-image.jpg" [1] => images/some/location/some-image.jpg ) This pulls the first instance, but none of the others. I think what the issue is... is that I am stopping after I get the first one, but I don't know how to grab the rest. Please help!! Thanks in advance, ~Philip
