How to show feature image as a 1st image on the product page and collection page.

[sahilrev]

Hi all,

I have an issue as I need to show the feature image as the 1st image on the product page, but unable to achieve the same as it is showing the variant image as the 1st image not the feature image(or first image which we have added  in the product admin section).

I have tried previous suggestion that has given on the forum but it is not working on the dawn 15.0 theme.

Also we need the same for the collection page, as for some of the product on the collection page its showing the feature image, but if the first variant is sold out then it is not showing the variant image rather than the feature image.

Can you all please help how can I solve this issue?

Hi @sahilrev Hopefully you have found the solution for this issue, if not then here is the code you can use to solve the issue of product page.

<script>
    document.addEventListener('DOMContentLoaded', function() {
    const allMediaItems = document.querySelectorAll('.product__media-item'); // All media items (big images)
    const thumbnailItems = document.querySelectorAll('.thumbnail-list__item'); // Thumbnails
    const featuredMediaId = document.querySelector('.product__media-item.is-active')?.getAttribute('data-media-id'); // Featured media ID

    // Function to display the initial featured image on load
    const showInitialMedia = () => {
        if (featuredMediaId) {
            // Check if the featured media exists and activate it
            const featuredMediaItem = document.querySelector(`[data-media-id="${featuredMediaId}"]`);
            if (featuredMediaItem) {
                resetActiveState(); // Clear previous active states
                featuredMediaItem.classList.add('is-active');
            }
        } else {
            // If no featured media, default to the first media item
            allMediaItems[0].classList.add('is-active');
        }
    };

    // Function to reset all media and thumbnails to remove active state
    const resetActiveState = () => {
        allMediaItems.forEach(item => item.classList.remove('is-active'));
        thumbnailItems.forEach(item => item.querySelector('button').setAttribute('aria-current', 'false'));
    };

    // Function to update the main media image when a thumbnail is clicked
    const activateMediaItem = (mediaId) => {
        resetActiveState(); // Remove 'is-active' from all media items
        const selectedMediaItem = document.querySelector(`[data-media-id="${mediaId}"]`);
        if (selectedMediaItem) {
            selectedMediaItem.classList.add('is-active'); // Activate the selected media item
        }
    };

    // Attach click event to thumbnails to update the big image
    thumbnailItems.forEach(thumbnail => {
        thumbnail.addEventListener('click', function() {
            const mediaId = thumbnail.getAttribute('data-target'); // Get the corresponding media ID
            activateMediaItem(mediaId);
            thumbnail.querySelector('button').setAttribute('aria-current', 'true'); // Mark thumbnail as active
        });
    });

    // Call the initial load function to set the featured image
    showInitialMedia();
});
</script>
