Can't strip these tags?

Hi, can anyone tell me why when I use the following code, it doesn't strip the html tags except for the ones indicated which should be left? In particular I'm trying to remove and <img> tags but this code doesn't seem to be doing the trick.

if(strlen($info[bodytext]) > $desc) { // Limit title length to avoid wrap
$bodytext = strip_tags($info[bodytext], '<a><ul><li>');
$bodytext = substr($info[bodytext],0,$short);
$bodytext .= "...[<a href=\"modules.php?op=modload&name=Journal&file=search&bywhat=aid&forwhat=$joid\">more</a>]";
}
else if(strlen($info[bodytext]) <= $desc) { // Limit title length to avoid wrap
$bodytext = strip_tags($info[bodytext], '<a><ul><li>');
$bodytext = substr($info[bodytext],0,$short);
$bodytext .= "...[<a href=\"modules.php?op=modload&name=Journal&file=search&bywhat=aid&forwhat=$joid\">more</a>]";
}

strip_tags() works on your offending tags.
Have a look at the source you are trying to strip and see if the < > signs are there, not & gt & lt.

Yes, the tags are there <IMG src....> and - but they aren't being removed....other ideas?

Have a look at these 2 lines and tell me what is happening.

    $bodytext = strip_tags($info[bodytext], '<a><i><b><ul><li>');
    $bodytext = substr($info[bodytext], 0, $short);

AHA, thanks, by isolating those two lines it came to me...I was taking the substring of the original text and not the text which had been stripped of tags. The lines should have read like this:

$bodytext = strip_tags($info[bodytext], '<a><ul><li>');
$bodytext = substr($bodytext,0,$short);

Simple error, must have been looking at it too long. Thanks for the help.

I thought that might help.
