Image licenses and authors not shown

[HerziPinki]

Hi, the app gravemap is great and fast in showing grave images found on Commons.

It would be nice (and necessary) if you could give the correct license & author information of the images acc. to CC-BY-SA licenses and similar licenses alongside with the images (not for the thumbnails, but for the larger popups). IMHO it is not sufficient to just link to the original description on Commons.
Furthermore, the website http://graves.wiki is using this package and is missing a clear statement of the owner of the website (e.g. an impressum). So I try it that way to contact you. If you are operating the website http://graves.wiki, could you please add clear contact information.

I'm a commons contributor, I have also uploaded grave images with CC-BY-SA shown by this package / app. So my intellectual property rights are infringed.
