How do we map product gallery images with variants in GraphQL ?

[Eligijus]

Hi,

I'm trying to map the product gallery images to variants to generate ALT texts and filenames for the media image based on variant data. But the product media response returns MediaImage or ImageSource ids and variant image returns null or ProductImage id.

Am i missing something ? How do I know which MediaImage is attached to what Variant on the same product ?

GraphQL code I use (v2024-10): 

query GetProducts($perPage: Int!, $cursor: String) {
    products(first: $perPage, after: $cursor, query:"published_status:published") {
        nodes {
            id
            handle
            media(first: 250) {
                nodes {
                    id
                    alt
                    mediaContentType
                    status
                    preview {
                        image {
                            id
                            url
                            altText
                        }
                    }
                }
            }
            variants(first: 250) {
                nodes {
                    id
                    image {
                        id
                    }
                }
            }
        }
    }
}
