I have been trying for half the day to figure out why my animation was being very difficult to do anything with. Since I did not get very far, I ended up deleting all of the keys and tried to start over. After deleting them, I saw that there was an image placed in the background. It is a picture of the model, but it is all over the place. I have no idea how it got there or how it is even remaining there when there are no active keys in the timeline. I did see that the timeline is still dark gray up until the 12 second mark without keys. I have tried to move it back and undo everything, but it does not go away. I have even closed it without saving, but it still remains in the background.  Are there any solutions for it? Any input would be fantastic! Thank you!
