    Hi all I am using the following custom function to display a thumbnail automatically taken from the first image in the post and it works great.

    <?php // This Function Powers the thumbnail image that is used in my portfolio
function return_ThumbNail($Thumb) {
if (preg_match('/<img[^>]*>/',$Thumb,$Treffer)) {
$Thumb = preg_replace('/(<img ).*(src=\'[^\']*\').*( \/>)/','$1$2$3',$Treffer[0]);
$Thumb = preg_replace('/(.[^.]* \/>)/','.thumbnail$1',$Thumb);
} else {
$Thumb = false;
}
return $Thumb;
}
?>

    I would like to extend this function to also pass the thumbnail the relevant “alt” text. I know this is probably simple but my php regular expression skills are not very good.

    Solved it myself

    <?php // This Function Powers the thumbnail image that is used in my portfolio
function return_ThumbNail($Thumb) {
if (preg_match('/<img[^>]*>/',$Thumb,$Treffer)) {
$Thumb = preg_replace('/(<img ).(alt=\'\').*(src=\'[^\']*\').*( \/>)/','$1$2$3',$Treffer[0]);
$Thumb = preg_replace('/(.[^.]* \/>)/','.thumbnail$1',$Thumb);
} else {
$Thumb = false;
}
return $Thumb;
}
?>
