Butterfly Picture FrameBorder

The demo shoes a frame around images with butterflies that match the theme. When I post pics I don't see an option to add that frame. Please help.

To set these frames around your images you have to set the featured images for your posts. Here is the instructions:

I'm so sorry, Alice; I just saw in the demo preview that this theme unfortunately has no frame around the images, which is only included in the theme, which I have already bought from you ....
