Sorry I think I couldn't understand what you meant, but investigating I found in vendor "module-catalog-widget", I put in my theme as, "Magento_Catalog_Widget" and put it inside ... / content / grid.phtml o even though I edited in list but it still didn't reflect anything in the home widget.

So do I necessarily need to save the image in the magento files and the bank? it doesn't seem to make sense ...

Thanks for the answer, that's exactly what I need

Thanks for the answer, I didn't find where the phtml with the tag <a> of the cart is, did you know the directory?

Yes, that solves, thanks

Thank you for that!

and how do i do that? I tried $resource->closeConnection();
