WP Clipart is a word processor-specific collection of public domain images, designed to assist users in their presentations or documents.
The creator of WP Clipart made some of the images, while the majority were acquired from several sources. These sources are all documented on the "Legal" page. One of the largest sources was OpenClipart, and the SVGs were converted using RSVG and scaled to proportions more appropriate for word processors.
Transparency was eliminated from the images as it avoids printing issues. Clips from other sources had their density and saturation levels adjusted to ensure they print well on typical home/small business inkjets. The midtones were opened up and large areas of shadow were eliminated to prevent blocking.
Scaling down the image sizes has the added advantage of a smaller download size. The files hosted on Ibiblio weigh in at approximately 79MB for the compressed package of all the clipart. More details can be found in the "Download" section.
Most importantly, all the images, illustrations and photos in WP Clipart are in the public domain. There are no restrictions for private or commercial use, and attribution or links are not required. These images are free to use in any way you like.
However, if you use these images online, the creator asks that you upload them to your own website instead of linking directly to their server. This prevents overwhelming their server and ruining it for others. On a positive note, the creator would be happy to post a "new clips page" in recognition of individuals who help to increase the diversity and quality of this collection.
