This extension is an example of how an extension to OpenOffice.org can make internet services available directly in OpenOffice.org. Clker.com is a website with free clip art. The site is funded by advertising. The service operates in the way that you register on the site and adding various clip art to your cart (you can also download them).
Through this extension to OpenOffice.org, you can retrieve your clip art directly into the document, without having to open your Web browser and download the images.
It irritates me a little, that the extension doesn't remember my account info from time to time.
