When you are building each web page, you also have top consider graphics. A page looks much snazzier with well-placed graphics on it. You can put the graphics on the page in any location you want as long as it doesn’t interfere with your text or other graphics. There has to be a balance. Also you need to know what type of graphic format to use. Browsers can handle all types but each type loads a certain way so you’ll have to learn the different types so you’ll use the right one. It would be a great idea if you go to
