Include artwork or images in a DITA topic by using the <image> element. The <image> element has optional attributes that indicate whether the placement of the included graphic or artwork should be inline (like a button or icon), or on a separate line for a larger image. An href attribute is required on the image element, as this attribute creates a pointer to the image, and allows the output formatting processor to bring the image into the text flow. To make the intent of the image more accessible for users using screen readers or text-only readers, always include a description of the image's content in the alt element.
