I’ve found Creative Commons to be a terrific source for freely reusable music, video and image content..
Beth Kanter, author of Beth’s Blog: How Nonprofits Can Use Social Media has provided a very useful list of additional free (or low cost) stock images that you can use for your own projects:
1. Flickr Creative Commons – Flickr is a photo site but it offers creative commons licensing and you can use it combined with keyword searches to find an image. I’ve been using this method for almost ten years!
2. Microsoft Office Clip Art Collection – This collection includes a combination of photos and illustrations and if you ever used the clip art option in PowerPoint, these will look familiar.
3. Morgue File – This collection of photographs were freely contributed by many artists to be used in creative projects. This collection was started in 1996 and you will find many beautiful images here.
4. Photoshare – This collection focuses on images that depict international health as part of the Knowledge for Health (K4Health) Project and was funded by USAID.
5. Wikipedia Public Domain Images – Wikipedia uses public domain images and has organized a collection with information on how the photos can be used and attributed.
6. Wylio – This is a searchable archive of public domain or creative commons licensed photos that bloggers can use.
7. Stock Exchange – This is a huge image archive of stock photos that are available for free.
