There are basic clipart illustrations that can work for the smaller or the less ambitious businesses out there.

There are fewer kinds of products on the market as business clipart that so fully embrace this old adage.
Pixabay's description of themselves is pointed and very clear. No technical jargon or fancy words to let you know that they offer free images. Their website says "Finding free images of high quality is a tedious task - due to copyright issues, attribution requirements, or simply the lack of quality. This inspired us to create Pixabay - a repository for stunning public domain pictures. Your source for free vectors, free drawings and free photos. You can use any Pixabay image without attribution in digital and printed form, even for commercial applications."
If the graphic is a vector image, it will be a snap to edit. Open the clipart image in your graphics editing program, select the area you don't want, and hit delete. It's that simple. However, bitmap images pose more of a challenge. You'll have to use the eraser tool and manually delete parts of the image. Or if you want to delete a section of solid color, you can use the magnetic lasso tool and press delete.
