Hi Jodie,
The 'members gallery' is your personal member's gallery here at Splitcoast.
To designate a card to a company gallery, you will need to use a designated company keyword. You can always see what keywords are used for any particular company by hovering your mouse over their company name in the company gallery listings. A little box will show up and indicate what keywords can be used for that specific company.
Does that answer your question?
