Secondary image URI data refers to a second or additional URI (Uniform Resource Identifier) that represents the location of an image on the internet. It is used as an alternative image source in case the primary image URI is not available or cannot be loaded.

In web development and mobile applications, using a secondary image URI can help ensure that users can still view the image content even if there is a problem with the primary source, such as a broken link or a slow server.

For example, a web page or application may have a primary image URI that points to an image hosted on a company's server, but if that image is unavailable, a secondary image URI can be used as a backup. The secondary URI might point to a similar image hosted on a different server, or it may be a lower-quality version of the primary image.

Secondary image URI data is typically used in conjunction with primary image URI data and can be specified using HTML or other programming languages. It is important to ensure that secondary image URIs are valid and properly formatted, to prevent errors or broken images from being displayed to users.
