Perhaps your new listing isn't all that photogenic. That is the case with many foreclosures and short sales, where the owner has not had enough money to properly maintain the property. One also sometimes takes on houses that really are a fright, because of accumulated possessions that litter every room.

To provide a sense of the house, minimally take a photo of the living room, the kitchen, and the master bedroom; these are key rooms for many buyers. If the house has interesting features, such as a sunroom or architectural detail, take photos of those, too.
To augment the number of photos in your listing, and to give a sense of place, include photos of the yard (if presentable), the street, and a nearby park.
