If your students are trying to search for photos / images in StoryJumper, but the photo results are blocked and aren't showing up, do the following:
1) Make sure you haven't turned off access to photo search.
On your class page, click "Edit Class".
If your Allow "Search Photos"? setting is set to "NO", change it to "YES"
2) If students still can't search for photos, please ask your school's IT group to unblock access to pixabay.com, which is where the photos come from.
