Re: img tags
in formatting-functions.php I added this under the function encode_bad:
$text = preg_replace('|<(/?img.*?)>|', '<$1>', $text);
under function bb_allowed_tags() I added this:
'img' => array(
'src' => array(),
'alt' => array(),
'title' => array()),
for an example see this post I made where it succeeded.
