Hey, @tashalong!
storefront i was using seemed to do what i needed but i never found a way to make the images fuller sized on the screen
For the product images, you can have the image keep its original size on Appearance > Customize > WooCommerce > Product images
But for the categories, it will remain 1:1/324×342.
As my colleague mentioned, you can switch to a theme that does not have this feature.
You can also look for a plugin that allows you to edit that.
You can search for “woocommerce category image size“, or something similar, on the Plugins > Add New section of your dashboard or on a search engine like Google, for example.
Please note that we do not provide support for third-party plugins, so it is good to check the plugin thoroughly to see if it is reliable. You can find more about this in this guide.
Another solution, and a more advanced one, would be to change this with custom code. While we also can’t provide support for code customization as per our support policy, we do our best to offer advice and direct you to appropriate resources.
You can visit the WooCommerce Facebook group or the #developers
channel of the WooCommerce Community Slack. We’re lucky to have a great community of open-source developers for WooCommerce, and many of our developers hang out there too.
I hope this was clarifying. Please let us know if there’s anything else we can do to help or if you have any questions.
Have a wonderful day!
