Scenario:
An instructor wants to include photographs or music in a PowerPoint presentation for his class lecture. Does he need to seek permission from the copyright owners to do so? What if he wants to make changes to the photograph or music file?

Response:
Because the use occurs in the face-to-face classroom, the instructor does not need to seek permission to use the copyrighted photographs and music files. Displaying or performing copyrighted works for classroom purposes is allowed under section 110 of U.S. Copyright Law.

In addition, changes made to enhance his instructional purpose, e.g. commentary, criticism, even parody, are activities allowed under the fair use provision.
