Hi,
1. I checked your site you installed ssl but your site link not yet update.
I go to Settings > General and change http to https, it now working

2. For product detail layout, i saw you select layout 3 product detail http://take.ms/DSFr2, if you don’t setup layout for separate product we recommend setup layout for all product in JanStudio > Theme Option > WooCommerce > Product Detail Setting.
If you still want use layout 3 you need change product image size by go to WooCommerce > Settings > Products > Display > Product Images
Change images’ dimension to fit with the content and regenerate thumbnail at Tools > Regenerate Thumbnail.
Best regards
