We have a built in custom HTML type module on Joomla 1.5 to use. That could be a handy module when we want to insert HTML tags or javascript codes like on an affiliate link. But have you wonder to insert a plugin you have and already works perfectly on your content articles into a module? Like a Youtube video plugin ( there's already youtube module out there). Give me some plugin examples that can't be applied on a module.

I have one example when I want to use TPFontReplacement plugin from TemplatePlazza (see it in action on their Folio Plazza) to be published on my header module position. As this plugin is only works on contents. So how to load it on a module?

The simplest one is to create a new content that contain this plugin code, just publish it in an uncategorized section/category. Then use CustomContent module to call this new content item.

I believe you already see this tips result when you first came here. Yes that's ugly photo on this Lab header module position above.
