How attribution works on Tank Talks
Each image used under a Creative Commons license is captioned with: a short description, the photographer's name as credited on the original Commons file page, a link to that file page, and a link to the specific license. The corresponding entry on this page repeats that information for archival reference.
Where an image is in the public domain, attribution is offered as a courtesy and is not legally required.
Where an image is licensed under a "share-alike" variant of Creative Commons (CC BY-SA), the share-alike obligation applies to modified versions of the image — cropped, recolored, composited, etc. A straight embed of the original image does not place any share-alike obligation on the surrounding article text.
