Just wondering if someone could help me write in a snippet of code which would make sure the link in between the [img] tags is infact an image.
How would i test to see if it was an image? I'm assuming i check the $1 variable, but how would i test to make sure they are using the [img] tag and not the [url] tag :X
$search = array('/\[b\](.*?)\[\/b\]/is', '/\[i\](.*?)\[\/i\]/is', '/\[u\](.*?)\[\/u\]/is', '/\[url\=(.*?)\](.*?)\[\/url\]/is', '/\[center\](.*?)\[\/center\]/is', '/\[img\](.*?)\[\/img\]/is');
$replace = array('<b>$1</b>', '<i>$1</i>', '<u>$1</u>', '<a href="$1" target="_blank">$2</a>', '<center>$1</center>', '<img src="$1" border="0">');
Any help would be appriciated
