This is IMG_COMP a language for creating images like photoshop but with a special syntax, its an image composition language, this language has strict sntax rules, but is pretty flexible in terms of usage.

If you use some text on the thumbnail IMG COMP, dont put the video title but 2 or three words that could trigger a click, always use $$variable_name for read variable.
