The word graphics on your question there is a tag. Every question must have at least one tag. For example, this question here has two, support and images.
Where you meant for there to be an image, there was the word "transparent" as a link to the image. To prevent abuse, new users are not allowed to embed images on a handful of large Stack Exchange sites including Super User. You will be to include embedded images once you reach 10 reputation. After that, the image insertion feature of the post editor will produce an embedded image, or you'll be able to use the syntax shown at the bottom of the formatting help page.
