Poster image not showing up in the poster window

Hello,

I've uploaded 10 images on a page, 9 still frames and one poster. All have been approved for publication, and are now listed in the "photos" section, 9 as still frames and 1 as a poster.

The problem is that instead of the poster, a cropped still frame is displayed in the poster window.

I've re-submitted the poster, it was approved again, and yet it does not show in the poster window. The same cropped still frame is there.

Is there any way to fix this, and make the poster displayed in the poster window ?

Thanks a lot,
