Use OpenOffice Impress as an image editor! Didn't know you could do this until I read Amit's article about Powerpoint!
You can change existing clip art graphics in Impress so that the image appears more relevant to your particular presentation. You can also combine edited images to create new graphics.
Once the image has been inserted in a slide, simply right click on it and select 'Break'. Then you can select the individual elements and move or delete them. When you are finished, join everything together again by right clicking on the image and selecting 'Group'. It's as easy as that.
Create all sorts of new graphics - limited only by your own imagination. Thanks for the tip Amit!
