image tags – ‘you may use’ instruction

That would be in the $allowedtags array in kses.php.

You would need to add:
'img' => array ('src' => array (), 'alt' => array ())
to that array.

Then you’d need to add the allowed tag to your theme so they know they can use it.

Alternatively, you could create some kind of filter which would let them use BB style img tags, or whatever other format you wanted.

Thanks so much for this! But what I meant was, where do I add it to my theme to let them know they can use it. I know it’s silly, but I just can’t find the text…

Try looking in your theme’s comments.php file. It should be there.

Thanks. Here’s what I suppose is the pertinent part in the comments file:

You may use
/<?php echo allowed_tags();?>
in your comment./

Which I assume is calling the text from elsewhere. Can you tell me where?

The very first line in Otto42’s post:

That would be in the $allowedtags array in kses.php.

Huh. I didn’t even know about that function.

Okay, so you don’t have you change your theme then. It’s automatic. Just change the allowed tags array like I described and see if that works.

Or just stick this into your wp-config.php file (despite what the kses.php file says in it, the my-hacks.php file won’t work for this application):

define('CUSTOM_TAGS', true);
$allowedposttags = array ('address' => array (), 'a' => array ('href' => array (), 'title' => array (), 'rel' => array (), 'rev' => array (), 'name' => array ()), 'abbr' => array ('title' => array ()), 'acronym' => array ('title' => array ()), 'b' => array (), 'big' => array (), 'blockquote' => array ('cite' => array ()), 'br' => array (), 'button' => array ('disabled' => array (), 'name' => array (), 'type' => array (), 'value' => array ()), 'caption' => array ('align' => array ()), 'code' => array (), 'col' => array ('align' => array (), 'char' => array (), 'charoff' => array (), 'span' => array (), 'valign' => array (), 'width' => array ()), 'del' => array ('datetime' => array ()), 'dd' => array (), 'div' => array ('align' => array ()), 'dl' => array (), 'dt' => array (), 'em' => array (), 'fieldset' => array (), 'font' => array ('color' => array (), 'face' => array (), 'size' => array ()), 'form' => array ('action' => array (), 'accept' => array (), 'accept-charset' => array (), 'enctype' => array (), 'method' => array (), 'name' => array (), 'target' => array ()), 'h1' => array ('align' => array ()), 'h2' => array ('align' => array ()), 'h3' => array ('align' => array ()), 'h4' => array ('align' => array ()), 'h5' => array ('align' => array ()), 'h6' => array ('align' => array ()), 'hr' => array ('align' => array (), 'noshade' => array (), 'size' => array (), 'width' => array ()), 'i' => array (), 'img' => array ('alt' => array (), 'align' => array (), 'border' => array (), 'height' => array (), 'hspace' => array (), 'longdesc' => array (), 'vspace' => array (), 'src' => array (), 'width' => array ()), 'ins' => array ('datetime' => array (), 'cite' => array ()), 'kbd' => array (), 'label' => array ('for' => array ()), 'legend' => array ('align' => array ()), 'li' => array (), 'p' => array ('align' => array ()), 'pre' => array ('width' => array ()), 'q' => array ('cite' => array ()), 's' => array (), 'strike' => array (), 'strong' => array (), 'sub' => array (), 'sup' => array (), 'table' => array ('align' => array (), 'bgcolor' => array (), 'border' => array (), 'cellpadding' => array (), 'cellspacing' => array (), 'rules' => array (), 'summary' => array (), 'width' => array ()), 'tbody' => array ('align' => array (), 'char' => array (), 'charoff' => array (), 'valign' => array ()), 'td' => array ('abbr' => array (), 'align' => array (), 'axis' => array (), 'bgcolor' => array (), 'char' => array (), 'charoff' => array (), 'colspan' => array (), 'headers' => array (), 'height' => array (), 'nowrap' => array (), 'rowspan' => array (), 'scope' => array (), 'valign' => array (), 'width' => array ()), 'textarea' => array ('cols' => array (), 'rows' => array (), 'disabled' => array (), 'name' => array (), 'readonly' => array ()), 'tfoot' => array ('align' => array (), 'char' => array (), 'charoff' => array (), 'valign' => array ()), 'th' => array ('abbr' => array (), 'align' => array (), 'axis' => array (), 'bgcolor' => array (), 'char' => array (), 'charoff' => array (), 'colspan' => array (), 'headers' => array (), 'height' => array (), 'nowrap' => array (), 'rowspan' => array (), 'scope' => array (), 'valign' => array (), 'width' => array ()), 'thead' => array ('align' => array (), 'char' => array (), 'charoff' => array (), 'valign' => array ()), 'title' => array (), 'tr' => array ('align' => array (), 'bgcolor' => array (), 'char' => array (), 'charoff' => array (), 'valign' => array ()), 'tt' => array (), 'u' => array (), 'ul' => array (), 'ol' => array (), 'var' => array () );
$allowedtags = array (
'a' => array ('href' => array (), 'title' => array ()),
'abbr' => array ('title' => array ()),
'acronym' => array ('title' => array ()),
'b' => array (),

'em' => array (),
'i' => array (),
'img' => array ('src' => array (), 'alt' => array ()),
'strike' => array (),

Undying thanks – this worked beautifully. I am sorry for being such an ignoramus and I thank people like you for providing instructions I can follow.
