My company wants to look into buying CD's or online access to a big library or collection of flash graphics. We would prefer vector graphics of course. We produce e-learning materials for large computer systems, so I guess we don't need butterflies and flowers but more stylistic icons for communication, information and computers etc.

I assume there will be no copyright problems once we have paid the price as long as we don'r resell the collection?

I have looked at this so far:

The images are okay I think but maybe you could suggest other site/products?

Also, do you have suggestions for good normal business clipart?
