Just replace full code with this:
<?php
/*
Plugin Name: Allow Images
Plugin URI: http://bbpress.org/#
Description: Allows <img /> tags to be posted in your forums. The image must be a png, gif or jpeg.
Author: Michael D Adams
Author URI: http://blogwaffe.com/
Version: 0.7.1
*/
// You can add more tags here
function allow_images_allowed_tags( $tags ) {
$tags['img'] = array('src' => array(), 'title' => array(), 'alt' => array());
return $tags;
}
function allow_images( $text ) {
if ( preg_match_all('/<img(.+?)src=("|\')(.+?)\\2(.*?)>/i', $text, $matches, PREG_SET_ORDER ) ){
foreach( $matches as $match ){
if (preg_match('/src=/i', $match[4]) /* multiple src = someone's trying to cheat */ || !in_array(substr($match[3], -4), array('.png', '.jpg', '.gif')) /*only match .jpg, .gif, .png*/ && '.jpeg' != substr($match[3], -5) /*and .jpeg*/){
$text = str_replace($match[0], '', $text);
}
}
}
return $text;
}
add_filter( 'pre_post', 'allow_images', 52 );
add_filter( 'bb_allowed_tags', 'allow_images_allowed_tags' );
?>
I think, it wont raise any security issues.
