Is there clip art that I can add into Keynote presentations?

I appreciate your reply and I've look at all of those tutorials in the past. But they don't tell me where there is stock graphic images / clip art that I can use. Microsoft PowerPoint has an extremely large and extensive clip art library that I can pull from (both online and offline libraries). Do I get anything like that will Keynote?

If you have the full Keynote package (that is, not the one included with iWorks), You will find the clip art under:

/Library/Application Support/Keynote/Image Library

Keynote does not rely on clip art since it has the Media library, so you will only find a few clip art in there (I know PPT has a few hundred and more for download). I remember that Steve Jobs said once that the reason why they did not pay much attention to clip art was because the images are usually low quality, out of date and most of their users wanted to use high quality images. So he left the clip art market open to other companies.

There are some companies who do sell or offer clip arts for free online, you can check out:

Also, for free photos and images the site I really like is Kepguru which features free high quality images.
