Legality of using images

[mistodin]

I am concerned with the legality of using images when curating an article

I am not thinking of artistic images from professional photographers where I would not even think to use them without authorization.

I am not talking either of pure affiliate products when the image owners gives almost full right to promote their product

I am talking of images of commercial products from e-commerce sites or e-magazines: new physical products, fashion products and alike.

Images would be used in a fair way: either a link to the shopping cart (eg: amazon) or at least proper credit with a real link.

I have always the option to use a deep link. I'd prefer to avoid that.

What is your experience ?
