Locating real royalty free images on the web can be a real pain in the tuckus. Thankfully, Paul Sherman has assembled a massive collection that he's happy to share with all comers.

WPClipart currently boasts 23,872 public domain images covering just about every subject imaginable. Most are offered as lossless PNG files.

You can browse or search for images on the site, and the five main categories (animals, holidays, history, signs and symbols, and cartoons) are available as individual downloads.

If you'd prefer to grab everything in one fell swoop, the entire collection is available as a single download. It weighs in at about 740mb and can also be downloaded from Freeware Files.

The full download also includes WPClipper, a handy viewer/editor application. It's also available on its own from the downloads section.
