Single out a piece of a variable

[Synned]

Hey
What I am trying to do is download html from a web page, and single out all of the images inside of it. So far I can already grab the HTML, I'm just at a lost trying to get all the images singled out. I don't know preg, what can I do? I can use strstr to get each instance of an image, but how do I tell it to stop? So in other words, how do I grab

<img src="http://dsafdshfadsf.adgfs/jdfs.jpg">

from a huge piece of HTML?

Thanks
Joe

preg_match_all('/<img\b[^>]*?\bsrc="([^"]*)"[^>]*>/is', $HTML, $matches);
print_r($matches);
