The Yale Face Database (size 6.4MB) contains 165 grayscale images in GIF format of 15 individuals. There are 11 images per subject, one per different facial expression or configuration: center-light, w/glasses, happy, left-light, w/no glasses, normal, right-light, sad, sleepy, surprised, and wink.

AR Face Database
This face database contains more than 130 people (around 70 males and 60 females). Everyone was asked to come twice to the Computer Vision Center, where the pictures were taken under strict controlled conditions. These two different sessions were separated in 14 days (two weeks time).

USC-SIPI Image Database University of Southern California Signal and Image Processing Institute:  The USC-SIPI image database is a collection of digitized images, which is maintained primarily to support research in image processing, image analysis, and machine vision. The first edition of the USC-SIPI image database was distributed in 1977 and many new images have been added since then.
