luceos I've been looking into this, actually maybe it could be a temporary solution as long as it is technically possible to bring the image through the API, I guess it is, just like bringing the description that is written on the Stripe product.
Anyway, on second thought I don't think it would be an ideal solution for the future of the extension as it would depend 100% on Stripe and if a new provider is added it would be a problem. Also, I'm not sure yet, but I think that image would appear on the statement of some banking applications which would be a bit weird.
Maybe it would make more sense to add the image to the indicated tag, on a button in the tag settings, this would at least not depend on Stripe or affect other providers.
