If image addon is installed, and you add a thumbnail to a thread, if you show that thread in a recent thread widget using full layout the image is showed twice, and one of them as full image If you disable image, the recent threads block looks normal again (see picture 2 below).
Ah right. It has a bit of a problem there which I haven't had a good solution for it yet. But you can avoid it by turning of the modification for [bd] Widget Framework in the [bd] Image option page. Or you can instruct user to not put any image at the beginning of the thread. Maybe I will add one more option to control support for Full layout.
