How to change product Thumbnail size to 1:1

Hi,

Product Photos used on your website are not square-shaped (they are rectangular to the top), so yes only additional CSS can help. A Small tip, class names used there:

.easystore-product-gallery button  {  }

.easystore-product-gallery button  img { }

Choose the Right CSS method, those are the options:

• `overflow: hidden`: Best for static cropping with full control over placement.

• object-fit: Ideal for responsive designs with consistent aspect ratios.
• clip-path: Use for creative shapes and advanced cropping.

For example

.easystore-product-gallery > button  {
  clip-path: inset(5% 0% 5% 0%);}

After using it

Whole rest is on your hands & keyboard.
