About IAPS: (from http://csea.phhp.ufl.edu/Media.html)
The International Affective Picture System (IAPS) is being developed to provide a set of normative emotional stimuli for experimental investigations of emotion and attention. The goal is to develop a large set of standardized, emotionally-evocative, internationally-accessible, color photographs that includes contents across a wide range of semantic categories. The IAPS (pronounced eye-aps) is being developed and distributed by the Center for Emotion and Attention (CSEA) at the University of Florida.

Disclaimer:
This database comes with a disclaimer, which you find here. The most important parts are cited below:

The International Affective Picture System (IAPS) is to be used exclusively in academic, not-for-profit research. It is expected that the pictures will be used only in basic and health research projects. In accepting these materials, researchers are expected
not to provide them to profit making companies or organizations. Furthermore, they are
expected not to make them available to the media (television, magazines, etc.), to publish the
pictures
(including in scientific journals or any other publication) or to place them on the
internet
. In addition to copyright and legal concerns, making these materials familiar to the
general public can seriously compromise their value as stimuli in many research projects.

Organization of the zip-file:
The pictures currently in the International Affective Picture System (IAPS) are included
in a folder/directory called “Images”. Each of these pictures is in JPEG format, labeled by its
IAPS catalog number and the .JPG extension (e.g. 1090.JPG). While the dimensions of any
specific picture might vary slightly, the maximum size is 1024 x 768 pixels. The pictures have
been digitally color-corrected and in some cases reformatted for monitor viewing.
The affective norms (ratings of pleasure, arousal, and dominance) for the pictures
currently in the IAPS were obtained in 18 separate studies involving approximately 60 pictures
each. The folder/directory called “Data” includes the files containing the normative pleasure,
arousal and dominance ratings (means and standard deviations) for the pictures 1) averaged
across all subjects, 2) averaged across male subjects and 3) averaged across female subjects. The files are in tab-delimited ASCII (plain text) format, and can be read by most text editors, graphics packages and statistics packages.
