Regex delete pattern

[richie]

How can I delete this pattern from a text message?

[img:bac3cd275b]http://www.mydomain.com/images/blue.gif[/img:bac3cd275b]
or

Basically, I want to delete anything inside:

or
[img:bac3cd275b][/img:bac3cd275b]

as well as the
itself.

The following did not work...
<?
$img_pattern = '[img(.)?](.)?[\/img(.)?]';
$message = preg_replace($img_pattern,'', $message);
?>

I believe this should work:

$img_pattern = '#\[img.*\].*\[/img.*]#Uis';
/*
# : pattern delimiter
U : Ungreedy matching
i : case-insensitive
s : include newlines when matching "."
*/

Thank you nogdog. That worked great.
