People silhouettes side-view. Currently people’s figures are very popular vector illustrations among stock sites and designers. Because it is easy to draw them and use, but they can make you graphics look much more cool-looking & eye catching.

It’s so easy to modify any vector file: change size, replace shapes, add other elements, change color, rotate. Vector illustrations can be opened in different computer art programs, for example: PMView, Corel Draw, Xara, Flash, Quark, and surely Any Adobe Software Illustrator, Photoshop, Indesign etc. can be used to open and edit vectors.

As for me, I prefer to use Illustrator CS3!
