Via block get custom type image or display default

Question

I want to display my new product image type in my phtml.

I use :

echo $block->getImage($product, "custom_type_image")->toHtml()

That work, but all my product didn't have an image with this type, so I would like, if no image was found, that display default image like :

echo $block->getImage($product, "product_base_image")->toHtml()

How to check ?

I can't check

if $block->getImage($product, "custom_type_image")->toHtml() 

is null because, if it doesn't succeed to find my picture, it create one as custom_type_image.jpg (which doesn't exist, so the picture is broken)

Answer 1

You check it by $product->getCustomTypeImage();

As it is a product attribute, it will give you value.
