Answer 1

Could you please confirm if your magento version is 2.2.4? You have error occured due to showCaption is empty. showCaption require true|false value. In your code showCaption:, look like this that why image is not load.

Please check following conditions.

1. Check your image has label present or not.

2. This error occured by overrides [YOUR THEME DESIGN DIRECTORY]/Magento_Catalog/templates/product/view/gallery.phtml file, it removes conditions from the gallery options

we need to modify the gallery.phtml that is overridden by the third party module or theme use below code
