For questions about the images used on StackExchange sites or about using images in your own posts.
Images on StackExchange sites should be included using the provided integrated image-upload procedure. Submission using this method has been available since August 2010 and is the preferred way to upload images. Using any other method (for example, manual upload IMGUR) may cause the images to be removed over time. Also, linking to an external web image is not preferred, since future image removal on the linked site would leave a broken link on TeX.SX.
