How to Add Image Thumbnail Column in Magento 2 Admin UI Grid – The Complete Method

When customizing Magento 2 admin panels, adding an image thumbnail column to your UI grid can significantly enhance usability, especially for product or custom entity listings. Instead of plain text filenames or image paths, showing a visual preview improves admin productivity and decision-making.

Why Add an Image Thumbnail in Magento 2 Admin Grid?

Adding an image thumbnail column in the Magento 2 admin grid enhances the backend user experience by providing visual context for image-based data. Instead of relying on image filenames or long text-based identifiers, a thumbnail preview allows administrators to instantly recognize products, banners, testimonials, or any custom entities with images. This visual aid speeds up workflows, reduces the chances of selecting the wrong item, and improves overall efficiency—especially for stores managing a large volume of image-rich content. By integrating thumbnails directly into the grid, Magento admins can make quicker, more informed decisions without needing to open each record individually.
