Regex help

[maqmus]

I got the following code:
preg_match("#=\"?((/?[a-z0-9_-]+/?)+.(html|gif|jpg|swf))\"?#i",$line,$matches)

I'm trying to retrieve file names from an array. With this code I can get "somefile.jpg" from <img src="somefile.jpg>, cause the pattern says to match the equal sign, double quote, name and sufix.

The problem is that in my case the array could be <img src="http://www.mydomain.com/folder/subfolder/somefile.jpg">

How should the pattern be to match just "somefile.jpg"?

preg_match("/<img src=\"(.*\/)?(.*)\">/i", $link, $matches);

$matches[2] will contain the filename. It works for both cases: <img src="somefile.jpg"> or <img src="http://www.site.com/folder/somefile.jpg">
