Below you will find the only sites that you can always get images from, unless you of course took them.
www.sxc.hu
www.freephotos.se
www.morguefile.com
www.openclipart.org
You can use WikiCommons only if the image has the proper info for fair use. If it does not than you will loose points on the assignment according to the rubric for that assignment. I found 40+ images in less than an hour for the 40′s.
If you find any more sites that are useful in this area leave a comment with the site!
