how to do this

[MarkFL]

I am thinking you will need to hack the file "/includes/class_bbcode.php" to include this extra HTML, if I am interpreting your question correctly.

Open that file, and locate the text:

PHP Code:

// Display the attachment with no link to bigger image 


Beneath this you will see the code:

PHP Code:

                                $replace[] = ($fullsize ? '<div class="size_fullsize">' : '') .
                                    "<img class=\"image\" src=\"{$this->registry->options['bburl']}/attachment.php?{$this->registry->session->vars['sessionurl']}attachmentid=\\1&amp;d=$attachment[dateline]$stc\" border=\"0\" alt=\""
                                . construct_phrase($vbphrase['image_x_y_z'], $attachment['filename'], $attachment['counter'], $attachment['filesize'])
                                . "\" " . ((!empty($align) AND $align != 'config') ? " style=\"float: $align\"" : '') . " />"; 


Now it's just a matter of adding the HTML markup you want.
