two relatively simple regexps

[kazer]

<a href="http://www.link.com/blah.html">link to blah.html</a>
turns into
<a href="http://www.link.com/blah.html">link to blah.html</a> [www.link.com]
should also support links like http://blah.com or http://127.0.0.1

<img src="http://www.image.com/image.jpg"/>
turns into
<img src="http://www.image.com/image.jpg" alt="http://www.image.com/image.jpg"/>

in the process if they could drop any other attributes that would rock.

fighting with it as we speak. (i suck with regexps)

$output = preg_replace('!<img src="([^"]+)" />!',"<img src=\"$1\" alt=\"$1\" />",$str);

That's what I came up with for the 2nd one. I wasn't too sure about the first. It looks like the message board messed up your code, so I didin't know exactly what to do.
