"First setup your Zentools module and give it a unique module position name (i.e. mygallery). Publish & Save these module settings and edit the article you want Zentools to show in. Where ever you want your Zentools to show within your article type,

{loadposition Your_Unique_Module_Position_Name}"

Thanks for the update

loadposition is a great plugin to use
