The Florida Center for Instructional Technology hosts two fantastic resources for teachers and students in search of clipart and pictures for classroom projects. One of those is ClipArt ETC and the other is Clippix ETC

ClipArt ETC is an online catalog of more than 70,000 pieces of clipart that students and teachers can download and use in classroom projects. The catalog is arranged in thematic collections and sub-collections. Simply pick a collection then a sub-collection to find the clipart that you want to use. The clipart is available in three file sizes to meet most needs. 

Clippix ETC is an online catalog of thousands of pictures teachers and students can download and use for free in their classroom projects. Like ClipArt ETC, Clippix ETC is arranged in thematic collections and sub-collections. Images are available in three resolutions to meet most needs.

Applications for Education
It’s important to note that these collections were built specifically for classroom use. That means that you shouldn’t encounter any images that aren’t appropriate for school. It also means that the licensing for the clipart and images is specific to classroom use. Use outside of the context of a classroom setting does require purchasing a license to re-use the images and clipart.
