Because of the focus on t-shirt designs, product zooms like this were often a necessity. That’s why I like WooThumbs. I think if you’re selling anything design-focused, you definitely need a zoom feature like this. WooThumbs implements it well, with good design and smooth functionality.
The only glitch I encountered in using the product was the video play button and follow zoom mode (which is probably a rare scenario). Everything else worked smoothly without any issues. The transitions on carousels look great, and I didn’t encounter any bugs with the zoom feature itself.
If you’re looking to upgrade your WooCommerce product imagery with carousels and/or zooms, you should definitely give WooThumbs a look.
