After searching for hrs on the support page I still don't understand how this thumbnail system works. It seems like the first media you add to the item will be used for the thumbnail but how do you not have it show up on the slideshow of the whole item page itself.
I want to have thumbnails for my videos, so that the videos will not play small in the portfolio page.

HELP!!!!!! shouldn't be this difficult.
Create a new thread and tell me what problems you are encountering and what you want to know. 
There is no step 3 :)
