BuddyPress Social Theme Gallery Homepage Featured Block

Hi,

I'm new here. I need help with the BuddyPress Social Theme. I have set the options to homepage featured block style to gallery. How do I get the image to appear in the featured block?

I've got the Slider working well and showing the featured post title and text but I can't figure out how to add the image that goes in the featured box.

Thanks in advance for any help.

Warm regards,
Lina.
