support data urls for thumbnails

[ycmjason]

Currently thumbnail supports URLs. I think it would be lovely if it supports data urls too so that I could have all my metadata in one single json, instead of pointing to a thumbnail file / url.

Thank you for this amazing tool btw!!! ❤️

Could you provide an example JSON that you might use if this feature were added?

ok, I understand what you mean now. I'm not opposed to this being added, but it's not something I will spend time on. Would you like to create a PR? 😄
