The picture you see next to the listing is a "gallery" image. I believe the cost for adding this feature is .35 cents, up from .25 cents not too long ago. It's only an extra click to choose this feature. I always add it when selling because I know when people are searching for items, they are more inclined to look at an auction if they can see at a glance what's being sold. Lots of people have short attention spans anyway, so it's helpful there too.
