Storing images in a central repository is a best practice in DITA content management. A central repository can be managed through a Content Management System (CMS) or a Digital Asset Management (DAM) system. This approach has several advantages, including content reuse, simplified version control, and enhanced access control.

First, it promotes content reuse. Images stored centrally can be referenced and reused across various documents and topics, ensuring consistency and reducing duplication. When an image needs an update, it can be done once in the repository, instantly updating all instances throughout the documentation.

Second, version control is simplified. With a central repository, different versions of images can be tracked and managed. This is crucial for maintaining documentation that’s consistent with software or product changes.

Third, access control is enhanced. Access to specific images can be granted or restricted, ensuring that only authorized users can modify or replace images.

Example

A software company that produces user manuals, online help systems, and technical documentation for its products maintains a centralized CMS where all images, such as product screenshots and diagrams, are stored. When a new version of the software is released, the updated screenshots are uploaded to the central repository. These images are then linked to various DITA topics in the documentation. If any of the images need modification due to changes in the software’s user interface, it’s done in the central repository, and all references in the documentation are automatically updated to reflect the new version. This ensures consistency and reduces the risk of errors, making content management more efficient and scalable across their documentation projects.
