Product Image Display Settings
How can I change the image to full size or adjust it?
Kim Welch At the moment, FluentCart does not have a built-in setting to switch product images between thumbnail / medium / large / full size from the Product Image Display Settings. What you can do right now is go to FluentCart Settings > Store Settings > Product Page. There, you can control: Enable Zoom, Enable Zoom In Modal, gallery/variation presentation options.
Only possible via custom code. I made an image optimization tool which uses a custom size and is visible on the front-end. Not yet publicly available. But I will release it soon.
