All images disappeared

Hi Ashley, thank you for your response. The course was originally built with Storyline 360. I had a bit of a crash while working in the course and that may have caused a corruption because the last half of the course didn't have problems with the images or audio. What was interesting is that even when I started a brand new project and tried to insert the images and audio files, they would also not appear or play. I followed another person's suggestion to rename the media files and that allowed me to change out the image files, so I have been successful in getting my course published. It would be helpful to know what might have caused it since there seems to be many people having the issue over the years. I will go ahead and repair Storyline to see if this prevents future problems. Thank you!
