User:-revi/Guide for banner from Flickr uploaded to commons

This is an essay. (note that this essay is not complete: Still working on it.)

While I was reviewing flickr file tagged for review (as an license-reviewer before being administrator, and now as an administrator on Commons), I saw lots of files based on flickr file, cropped for banner, and improperly sourced, so improperly tagged as NO SOURCE. Most of you use only (Commons template) or  (Commons template). Like

Because there is no flickr link in  parameter, commons' flickr review bot (named FlickreviewR) always fails to confirm this file, and needs additional work. You have to make like this:, so reviewer can.

Sometimes, you source file like [//commons.wikimedia.org/w/index.php?title=File%3AShimokita_Night_wikivoyage_banner.jpg&diff=115454165&oldid=115433266]. You should also avoid to do so, and do like, so reviewer can.

This reduces redundant works, and I and reviewer can spend less time on this reviewing, and spend more time for find copyright violations, close deletion requests, and etc.
