We are changing the way images and other media assets are handled by this website. We hope that will make it easier for content creators to insert images and video into the webpages they create. This change will allow both uploaded content and content resourced from other websites (YouTube, Vimeo, Flickr, etc.) to be managed and reused, seamlessly we hope. This change will primarily affect the interface used by forum posters but is not limited to forum posts — other content creators will be able to take advantage of this new interface as well.
For normal web users, this change will likely go unnoticed.
