Shopify's product image gallery holds many images per product, but in practice buyers engage most with the first few. A crisp before-and-after grid placed in position 2 or 3 catches attention after the main shot and delivers proof before the buyer scrolls to reviews.

The classic format is a 1×2 horizontal split: the 'before' state on the left, the 'after' on the right. For supplements, skincare, or cleaning products, this can show: dull skin vs. glowing skin, stained fabric vs. clean fabric, cluttered desk vs. organized setup. For physical transformations like fitness equipment, the same layout works vertically (top / bottom).

MergeFrame lets you set a custom gap between panels: even a thin colored line between the two sides acts as a divider and makes the comparison feel intentional rather than accidental. Use the same aspect ratio for both images before uploading for a clean 50/50 split. Shopify's recommended size is 2048px; exporting at that dimension ensures the zoom function is crisp on Retina displays.
