By default, the FKX theme is the only theme with Product Image Glow enabled by default. To enable this feature on any other theme, you must enable it by going to Code Snippets under the Page Builder section in the Admin Area. Find the entry that says “Product Image Glow” and enable the switch. The feature has now been enabled.
From there, click Customizer under the Theme section in the Admin Area. You’ll be taken to the WordPress customizer. Click WooCommerce, and under Modules, look for an entry that says “Product Image Glow“. From there, check the box to enable the glow and customize the color.
For best effects, please make sure your image is transparent (either .gif, .png or .webp). If your image is not transparent, the entire image box will glow instead of the outline of the product.
