Flickr users have reported that a number of their photos intended for just friends or private viewing have been visible to the public eye for almost a month now. However, Flickr claims that these images were only accessible if you had a direct link, meaning Flickr searches or Google searches would not have exposed your photos. Flickr’s vice president Brett Wayn claims that only a small number of users have been affected and the issue has already been discovered and fixed.
To make matters worse, Flickr has changed any potential photos that were affected to private, which also annoyed some users who now have to go back and change settings on their photos from years ago individually. While there is not a quick way to be able to identify exactly which photos were impacted, you can head over to your statistics page and possibly go through your photostreams for a check-up.
