Hi @M123-dev!
Not very convinced: of course it probably solves the issue (a screenshot would be nice), but the Image is therefore probably a bit little.

Possible improvement: use the RRect like in the product items in lists.
Not sure if it's much bigger, but at least it's vaguely consistent with the rest of the app.

[monsieurtanuki]

That's not that big. Probably ridiculous for images in height.

Thanks for the review @monsieurtanuki, I added the RRect and changed the size back to 50 as this will be changed anyways by #2843
