There are many places to find nice backgrounds for a yearbook, including through the yearbook publisher or on Pinterest. Artistic students at the high school are often willing to create original backgrounds and contribute other art for the yearbook.
Some yearbook publishers offer backgrounds and other art for free as part of the cost of publishing the yearbook, explains Yearbook Life. This is advantageous because it costs nothing extra and the publisher supplies popular layout designs for the background. Pinterest is very useful for gathering ideas and images, but users must beware of the possibility and danger of using copyrighted images someone posts. Using student artists for interior art has the advantage of making the yearbook feel more like a student creation.
