Steps to replicate the issue (include links if applicable):

• Upload a photograph from Flickr.
• Make sure {{Flickrreview}} is appended.
• Wait for automatic license review by FlickreviewR 2 bot.

What happens?:

• The bot frequently return failed license review result as "size_not_found". Usually this should only happen when someone uploads a cropped down version.
  • An example can be found at here: it took 7 repeated attempt to finally pass the file's review.
• Repeatedly requesting the bot to review through {{Flickrreview}} usually fails, but sometimes it might pass after many reviews.
• It appears that the problem happens intermittently: often the bot may pass a few files, then followed by a swath of failed reviews, and so on.

What should have happened instead?:
As long as the size and file type are exact, The photograph should be reviewed quickly.

Other information (browser name/version, screenshots, etc.):

• The bot owner was not active for the past month, so we can't directly ask for assistance.
• MGA73 has acted by instructing MGA73bot2 to made automatic new review requests.
• According to Zhuyifei1999 (on an inactive bot nomination on Chinese Wikipedia), the was a bug in YiFeiBot (FlickreviewR 2 is run on ToolForge as YiFeiBot) in which it was later fixed. I am not sure whether this is related.
