I can't find any information for this on the documents.
This is such a simple feature to implement.
Hello Cody, thanks for reaching out. To filter for unfilled image fields in Prismic, you can search for the image field by its API ID and find the empty object. While this method might not be documented explicitly, it effectively identifies documents with empty image fields.
Can you elaborate please? Thanks.
Of course. The API ID is the name that you give to your fields when creating the content modeling of your pages. For example, an Image field could be named background, profile_picture, logo, etc. On the API response, this value is a metadata field that formats and stores a human-readable, SEO-friendly identifier for each field in your pages, unique to the Custom Type.
