Trouble with Content plugins

Hi, im having trouble with content plugins in my articles.

The wall im making calls long articles that contain galleries and videos. These galleries and videos are inserted with tags using content plugins.

These tags are by example [bt_youtube url="" width="600" height="450" responsive="yes" autoplay="no"][/bt_youtube]

So... When the wall loads ... takes a lot of time loading the whole articles ... and worst ... it goes to youtube to load content ...

I have disabled the parameter: Joomla! content plugins ... but is not working.

What i would really like is to display only the intro text where i can put an image and title and get rid of the rest of the article without loading and of course without going to look for content in the galleries and youtube.

How can we do it?

Thanks in advance
Luis
