The Catalog is a simple yet very complete Tumblr Theme focused on getting all your photos, text, videos, audio in a catalog-like format. All posts are showed as thumbnails and you can see more by clicking them. It’s a responsive theme that works well in different screen sizes. It has a slider that fetches posted photos based on a special tag.
