create_google_image_extension

Attach visual imagery (1-20 product / lifestyle shots) to a Google Ads text ad to lift click-through. BETA. Re-uses assets already uploaded to the Metadata image library — pass their IDs, not raw files.

                ALSO KNOWN AS: image extension, image asset, ad image, visual extension, picture extension, photo extension, hero image

                KEYWORDS: image, image extension, photo, picture, visual, hero, asset, library, BETA, google ads, extension, CTR

                WHEN TO USE:
                - "Attach images to our Google Ads text ad"
                - "Add image library IDs 123 and 456 as an image extension"
                - "Create an image extension showing product photos under our search ads"

                WHEN NOT TO USE:
                - The image is a logo / brand mark → use create_google_business_logo_extension
                - You haven't uploaded the assets yet — image extensions reference library IDs, so upload to the image library first.
                - Want to drive clicks via text snippets → use create_google_sitelink_extension / callout
                - Same images for Microsoft Ads / Bing → use create_microsoft_image_extension

                INPUTS:
                - image_library_ids (required): 1-20 IDs from the Metadata image library.
                - alternative_text:  accessibility alt text (≤90 chars).
                - display_text:      short caption overlaid on the image (≤35 chars). E.g. "Shop Now".
