Yes! The International Affective Picture System (IAPS) is widely used.
From the IAPS instruction manual:
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), along
with the International Affective Digitized Sound system (IADS), the
Affective Lexicon of English Words (ANEW), as well as other
collections of affective stimuli, are being developed and distributed
by the NIMH Center for Emotion and Attention (CSEA) at the University
of Florida in order to provide standardized materials that are
available to researchers in the study of emotion and attention
The stimuli are completely free, but a request must be made by a faculty member (rather than a student). The reason they give for this is that "Making these materials familiar to the general public can seriously compromise their value as stimuli in many research projects."
You can request the stimuli here.
