I know that links to images online are discouraged. If the link breaks, the question loses its content.
This is all about this question, but there's a general problem behind it.
- I followed the link, and added the image to the question. I used "link from the web" for that. This uploads the image to imgur. Which is independent from the original source.
- The author of the question (Blackbird) changed the included image to being sourced from its original source and asked if I can take the image down from imgur, because I was breaking his copyright in uploading it there, which also conflicts with their terms of service.
- I stated that my intention is not to break any copyright, but to ensure the availability of the image in the question. I was hoping that using a source that is considered reliable is in the intent of the author. It was not.
- Is this special case a copyright infringement or fair use?
- How can I remove the image from imgur?
- How should this conflict be resolved in general? Moving an image to a "reliable" source means possibly breaking copyright. Should images be removed entirely if including them in the post is not possible due to possible copyright conflicts like this one?
When making an edit that includes images, force the edit to be either approved or rejected by the original author. If approved, the image is uploaded to imgur, by that approval and not the original edit. This way, there's no copyright problem, because there's no copyright being broken (not even with good intentions) and the image has an independent source from the original one.
