Adding a picture at the end of the video

Lindsy Posts: 3 Just Starting Out

I want to add a picture at the very end of my video and add some text to it. I cropped the picture to wide screen size, I created a composite shot, added some text, but in the 'Viewer' panel and even after exporting the whole video only the very center of the picture can be seen. Basically I wanted to add a picture of my cat, but you can only see her face enlarged on the screen. How do I fix this?
