How to change the size guide's image?

You can create your own size guide chart and add it to the products in your store.

Here's how to do this:

1. Open a product page in the theme editor.

2. On the menu on the left, expand the 'Product Information' item. Inside it, you'll see the 'BMP: Size guide'.

​

3. Expand the Size Guide and click on the first 'BMP: Size guide image'.

​

4. Replace the default size guide chart with the one you have created.

​

5. The new size chart will automatically apply to all products that have their Product Type set as 'T-shirt'. Don't forget to save the theme to verify the changes.

If you're selling a different product instead of T-shirts, make sure the Product Type matches your specific product. You can also click here to learn how to add different size guide charts to different product types.
