If you can sit still a minute and read this you will learn to be cool, and stay out of legal trouble, when dealing with graphics on the Internet. You might even make the great leap into becoming a graphic artist yourself and find employment and satisfaction for years to come. If you take graphics and put them on a commercial web site and have not made arrangements to compensate the original artist, you're stealing.
Real webmasters take care of their own.
They make sure graphic artists are compensated for profitable work. They are anywhere a graphic artist chooses to make them available. Maybe you talk about yourself and your life. Maybe you put up a web site that is a family history. Maybe you build a web site that goes in depth about your favorite hobby or sport.
