Hi, When supplying images that have a larger width or height than 50 pixels, the API just returns with {"error":{"message":"imgs width invalid","details":[]}} Why is that? Also this is not stated anywhere in the docs, could save some headache.

Hi, Legal guidelines regarding the use of Web Snapshots are hard to find, so this is why I'm asking the following: a) Is it allowed to cache images on your own server. If not, what about the scenario where a snapshot gets crawled and then cached by google or facebook (when shared as a preview image on a timeline for example) b) Is it allowed to compose additional graphics on a snapshot, that being only possible if (a), the possibility to serve a local snapshot is given.
