You may add images, media materials, “interactive” elements (visualizations, maps, games, etc.) to your Manifold project. These are referred to as "resources" within Manifold. Files can be loaded directly into Manifold so long as they do not exceed 200 MBs. All common image, video, audio, and text file types are supported, and you can find a full list of approved file types and instructions on preparing your file types, please visit the Manifold Github manual page.
You can group your resources together into collections to create image galleries, or bring different types of resources on the same theme together in one place.
Once you have texts and resources uploaded to your Manifold project, you can embed resources into your texts to add context, depth, and interactivity to your texts. For example, if your text references a particular neighborhood in Seattle, you could embed an image of a map of that neighborhood in that section of the text for quick reference. You can embed any of the supported resource types into your texts.
Detailed and accurate metadata values provide valuable context for users, making resources more findable, meaningful, and useful for them. Good metadata will also make it easier for you to manage your project as an administrator. For guidance on the available metadata fields in Manifold, see this Manifold page about metadata.
Another thing you should consider is adding alternative text or "alt text" to any images that you add to Manifold. Alt text is a written description of an image that conveys an equivalent message for people who cannot see the image. Alt text makes the images on your manifold project more accessible to screen readers.
