Should I use real world images in e-commerce?

I work in a skincare company and I lately came into a discussion about whether our E-Commerce images should be representing the real dimension of containers or a scale of them (200 ml, 100 ml, 50 ml).

So basically, the same frame of 500px * 500px would display different proportions depending by the item.

Assuming that this could be possible for certain products on some screens, I found this extremely complicated, non-usable and difficult to maintain, also from a software perspective.

I didn't find any relevant resource about this topic, on which I'm reluctant. Following some best practice I always see full dimensions and eventually explicable guides to sizes, like amazon does for books.

Should I use real-world scale images in e-commerce?
