Adding images under product photos on a product page

I would like to add an image underneath the product photo carousel on the right-hand side of the product page. Ideally, I'd like this image to be inline with the product photo block above it, and I'd like to have the option of adding a photo here on all product pages. The candle pages are most important, however, and they are all under the Shop category "Candles".

The shop is currently password protected with the password "adminonlyvip".

Note: I already have custom code in place to move the Accordion block below the product description, as long as the Accordion block is the last item in the Additional Info area.

Hi,

What is site url?

My approach is you add an Image Block to Additional Info, then we will use code to move the image to that position
