I actually just did this in includes/class_bbcode.php look for the following function I added the red part to fit my forums fixed width.

function handle_bbcode_img_match($link, $fullsize = false)
	{
		$link = $this->strip_smilies(str_replace('\\"', '"', $link));

		// remove double spaces -- fixes issues with wordwrap
		$link = str_replace(array('  ', '"'), '', $link);

		$retval = ($fullsize ? '<div class="size_fullsize">' : '')  . '<img width="920px" src="' .  $link . '" border="0" alt="" />' . ($fullsize ? '</div>' : '');

		($hook = vBulletinHook::fetch_hook('bbcode_img_match')) ? eval($hook) : false;

		return $retval;
	}
