solved: DVR 15: Show picture in fusion over clip

Hello.
I need to distort a subclip. That works perfectly in fusion. In fusion, the subclip is shown as a range of the original clip. But the distortion must match to what a picture shows. So I try to show that picture in 50% opacity over the clip, or at least as a media input in the second preview. If I go to fusion with the clip selected, I can drag the picture from media pool to the node window. The picture is shown on position 0 of the timeline, not where the subclip starts.
How can I get the picture shown over the subclip?
