Well, in that case - we can go with "wikimedia_commons:1" and "wikimedia_commons:1:path". That perhaps looks a little better. 

Btw, can you link the tags:1 which are approved? I don't know how to find it :) In taginfo i looked for "image", "url" etc. but they are not that significant.

Also should we start with :1 or :2 ? 🙂🤔
