If the module is true 1.5 compatible, copy the template file from
modules/mod_module/tmpl/default.php to
templates/template_name/html/mod_module/default.php and customise there.
Some modules are not compatible, quickest long term solution is to
- embrace module with unique html comments in template
- write a system plugin (write 2 files and copy/modify one database line)
- use something like:
jimport('joomla.application.menu');
jimport( 'joomla.plugin.plugin' );
class plgSystemLeftmenueffect extends JPlugin
{
var $_db = null;
/**
* Constructor
*
* For php4 compatability we must not use the __constructor as a constructor
for plugins
* because func_get_args ( void ) returns a copy of all passed arguments NOT
references.
* This causes problems with cross-referencing necessary for the observer
design pattern.
*
* @access protected
* @param object $subject The object to observe
* @param array $config An array that holds the plugin configuration
* @since 1.0
*/
function plgSystemLeftmenueffect(& $subject, $config)
{
parent :: __construct($subject, $config);
}
function onAfterInitialise(){
$document =& JFactory::getDocument();
$document->addScriptDeclaration(
"window.addEvent('domready', function() {
$$('.leftmenu li.parent ul').each(function(el){
var myFx = new Fx.Slide(el);
myFx.hide();
});
$$('.leftmenu li.active ul').each(function(el){
var myFx = new Fx.Slide(el,{duration: 2500});
myFx.slideIn('vertical');
});
});
");
}
function onAfterRender()
{
global $mainframe;
if ($mainframe->isAdmin()) return;
$content =& JResponse::getBody();
$found = substr(
$content,
strpos($content,'<!--leftmenu_start-->'),
strpos($content,'<!--leftmenu_end-->')-strpos($content,'<!--leftmenu_start-->')
);
$content =
substr($content,0,strpos($content,'<!--leftmenu_start-->')).
$found.
substr($content,strpos($content,'<!--leftmenu_end-->'));
JResponse::setBody($content);
}

No. My solution is to:
- write backend plugin that injects button into backend screen (see above,
same technique)
- write simple backend component that handles the user interface to edit
image)
Simpler version:
- write backend plugin that injects parameter field into Joomla sidebar
(most components have parameters)
- Joomla or component handles parameter saving

Hacking the module...
As above, not necessary and not the right approach, thanks.

Berend is not known being a big Joomla fan and given the amount of things I
get him to fix on our Joomla sites that is probably not going to improve.
We have our friendly debates however, his criticisms are sound (albeit
incomplete, ey Berend!)
