Reply To: [Waiting for user confirmation] Responsive View Grid

I manage to set 3 different views: 1 for Desktop (3 columns grid), 1 for tablet (2 columns grid) and 1 for cellphone (unordered list). I use php if then else to have each view displayed in the right device. But my problem is this: it works perfectly but when I use it for WP RSS Plugin, I cannot display the featured image of the feeds. Help needed on that issue please.
