So far I just can’t get it done.. I’m trying to get the field “cursusfoto” (see http://d.pr/i/ibk3) set as the featured image. I already set the return value at the ID (I assume that’s right), see http://d.pr/i/q6nJ.
However, I simply have no clue how to manage this code-wise.. (I’m not a developer).
