In Sitefinity there is a dedicate approach for managing media content like Images, Videos, Documents and Files that should be displayed in the client side of the site. Using it will allow you to better organize your media content, store meta data (author, description, etc.), introduce workflow (drafts, published content, etc.) and provide easier access in the client side for that content using the dedicated widgets. Please find more detailed documentation here
Is this approach viable for your needs?
