Yes, you replace with the name of the account you want to use for your bot. If you want to see it in action, there's an exifr account that is running. See

It is not using post support yet though. Before post support is working, on exifr I am trying to get a public configuration page working for people to use and signup using steemconnect. Follow the bot, and you will know when it's enabled.

Thanks for your prompt reply. I also read your other post few days ago. That means, to mention @exifr in a post will get a comment with the meta data of photo? Does it work for the first photo or multiple photos of the same post? Sorry for too many questions because I am interested in your work :)

For now, you want to mention @exifr in a comment (not a post). In the future, @exifr will support posts. Also, at this time, just the first photo will get exif data. Steem users thought it was too much spam. In the future, each photo will get exif data. Here's an example https://steemit.com/photofeed/@r351574nc3/drama-for-drama-sake

The second photo got exif data only because the first had no exif data at all. Each photo will get exif data. Sorry if this is confusing. To make it short:

  1. Exif data in comments and only on one photo is how it works now
  2. Next version will support @exifr in posts, data in posts, and all photos for the post.
