Facebook links misplaced downwards and how to decrease gaps

Good plugin, nice one.

Please help how Facebook links misplaced downwards be fixed (the links are overlapping image – a workaround is to leave a blank line while posting new topic) and how to decrease gaps as in the below snapshot.

And how to change the default al2fb_image=1 to any other image ie; al2fb_image should always take pages own photo or sites default photo instead of W image ie; in the new post page, instead of the big W image showing up or being added up, posts image or if no post image exists then sites default image or logo should be there.

Thanks a lot in advance.
