I wanted to set a featured-image, so I tried the following, but it couldn’t be rendered.

%%featuredimage
%%featured-image
%image

I also tried the FIFU code, but it didn’t display.

%fifu_image_url
%fifu_dev_set_image


Is there a code snippet to make a featured image, or FIFU image, appear in a forum topic?
