I'll let you figure that one out for yourself. I really don't recommend it. Blinking objects are very annoying, and they just make people think you're a jerk. Only use blink when you want to call attention to something that is terribly important, and preferably a new addition, like the test has been canceled. In class we talking about inserting images into a document.
Images do a nice job of making pages attractive, and they are easy to insert.
Try not to use big ones if you don't have to, because they take longer to load. The first problem is where you get an image from. What a great lead in to inserting a picture of my granddaughter and my grandson. If you live in Juneau you don't let a little cold rain stop you from anything. At least he has a jacket on this time.
