deleting images

i inserted an image on to my homepage by clicking on “set featured image”

I selected to place the image on the top right side of the page. it came out on the top left side. so then decided to get rid of it by clicking “remove featured image” and it wouldnt go away.

so i went into the gallery and deleted the image. now my homepage has a thumbnail on the top left side. how do i get rid of it?
