Manage assets
The Uniform asset library offers convenient access to a common set of assets to drive your experiences.
The asset parameter comes with all the meta data needed to provide an optimized web experience. It's more versatile and powerful than the legacy image URL parameter, which adds a simple image URL for inline linking to a component.
Content and technical architects, or anyone responsible for configuring components can add the asset or image URL parameters to the component definition. Team members responsible for creating and editing compositions will use the asset and image URL parameters, and manage assets in the asset library. Permissions for each group may differ.
Assets#
The asset parameter supports adding images and common media file formats for audio, video and documents to a composition or entry from different sources, including the Uniform asset library, data resources, and inline linking. The parameter may be configured to allow for multiple assets to be selected. Each selection includes built-in metadata (for example, a caption).

Image URL parameter no longer supports uploads
As of March 11, 2025, image uploads via the Image URL parameter are no longer supported.
Any previously uploaded images used in Image URL parameters will continue to function normally, but you cannot upload new images through this method.
For all image upload needs, please use the Asset parameter, which provides improved asset management capabilities.
This parameter adds inline linking to an image URL in a component. It supports uploading images as channel-specific, composition-specific assets.
