@TASHLY - you can still share the link by clicking preview of the theme on which you are working, then I can check this modal and check code to find way to increase image width.
Thanks for trying my friend… but sadly still no solution…
I will keep this thread open in-case someone else has a solution… hopefully Shopify themselves will have an update where this option is built into the
“Buy Button” customiser under the “Detailed Pop-up” section.. where you can choose image sizes when using the carousel option – it seems like a very simple option to have, but not available…
I managed to change the size of the image by downloading the javascript from shopify that the buy button script points to and modifying that javascript. But sadly something has changed that I can’t find a workaround for and I can no longer point to a custom javascript on my own server instead of the one on the shopify servers so a feature like this will have to be implemented by Shopify developers.
