This script was made to automate the process of preparing student photos for import into PowerSchool. Mostly used for students who enroll after picture day.  The script assumes that you are taking a standard portrait with the camera turned 90 degrees clockwise (or a vertical picture with your right hand on the bottom of the camera).   Once the student pictures are taken, you would copy the pictures from the camera to your computer and run the script, at which time it would:
1.  Ask you to select the photo or photos you wish to prepare for PowerSchool.
2. Rotate each photo 90 degrees (so it is right side up), scale the photo down to 300 pixels length wise (if it is larger than that), and convert the photo to JPEG if it is not already.
3. The new images will have a "PS" added to the end of their name, and a copy of the original file will be in the trash.
