How to provide attribution to a media source in a research paper? I'm working on a project report which we plan to publish as a research paper later after some more work. In my report I have used some images from the Wikimedia Commons and Wikipedia. They all are either in the public domain or licensed under the Creative Commons license.

I would like to provide attribution to the media source in the report and the paper. I have googled it but could not find a source which explains it with an example.


Is there a standard way of providing attribution in a report/paper?
Can I provide attribution in the  bibliography along with the cited papers?
I'm using bibtex for references. Is it possible to handle the media attribution using bibtex?
Does anyone know of a published paper which provides attribution to the media sources so that I can have a look?


EDIT:

Does anyone know of a proper way to provide attribution in captions because I think attribution in captions will reduce readability.
Why don't you provide a list of media sources in the appendix similar to the obligatory literature list.
You number the images anyway inside the paper, so you can easily reference them in an appendix. Depending on your textprocessing tool you also can generate backlinks to the images for hypertext reading.
This could look like this:
