The bulk update request #9751 is pending approval.
remove alias picture (0) -> photo (8139)
Reason: So picture aliases to photo (alias #2331), but with no associated forum thread.
Dictionaries say a picture is a drawing, painting, printing, photo, etc.
https://en.wiktionary.org/wiki/picture
"1. A representation of anything (as a person, a landscape, a building) upon canvas, paper, or other surface, by drawing, painting, printing, photography, etc. "
https://dictionary.cambridge.org/dictionary/english/picture
"a drawing, painting, photograph, etc.:"
Suggest
1) picture no longer alias to photo.
and
2) for BUR part2: pictures tag alias to picture.
painting wiki says "This tag is ... for images where there is a painting of some sort visible within the image. Often, such a painting will be within a picture frame which should also be tagged."
