I believe that Shapeways partially leaves photo resizing to the browser. This mostly works fine, but for my most recent model the picture is not treated nicely by IE (see attachment).
I just noticed it happens on most of my other photo's as well. They all look fine in Chrome but look mangled in IE.
I don't want to scare away people by showing them a mangled photo of my product so I fixed it by uploading a picture that was exactly the right size. Consequently, the zoom functionality is lost.
I would prefer to upload slightly oversize pictures and have Shapeways do the work. So, Shapeways, please resize our pictures properly!
