5.2. 2. Vector-drawn graphics
5.2.1. -Applications of vector-drawn objects
5.2.2. -How vector-drawn images work
5.2.3. -Vector-drawn images versus bitmaps
6. 3 basic group legal rights protecting use of images from clip art galleries
6.1. 1. Public domain images
6.1.1. -either never protected by a copyright or their copyright has ended
6.2. 2. Royalty-free images
6.2.1. -purchased and used without paying addition license fees
