Instead of using each resource contributor's avatar in the Resources listing page, allow to use a thumbnail of each resource's attached image to show up in Resources listing. If multiple images attached for a resource, allow user pick a cover image to be used in the listing. If no image attached, then allow admin to offer a default one(universal).
I thought of this as I figured, in lots of situations, a picture of each particular resource speaks louder than the resource contributor's avatar.
Thanks in advance for considering.
