Understanding frames and keyframes is essential for mastering Flash. Be sure you
understand how the photo2 layer contains 48 frames with 2 keyframes—an empty
keyframe at frame 1 and a filled keyframe at frame 24.

frames 1–23

frames 24–48
Moving a keyframe
If you want your photo2.jpg to appear later or earlier, you need to move the key-
frame in which it appears later or earlier along the Timeline. You can easily move
any keyframe along the Timeline by simply selecting it and then dragging it to a
new position.
1 Select the keyframe in frame 24 on the photo2 layer.
2 Move your mouse cursor slightly, and you’ll see a box icon appear near your
cursor indicating that you can reposition the keyframe.
3 Click and drag the keyframe to frame 12 in the photo2 layer.
The photo2.jpg now appears on the Stage much earlier in the animation.
Removing Keyframes
If you want to remove a keyframe, do not press the Delete key! Doing so will delete
the contents of that keyframe on the Stage. Instead, select the keyframe and choose
Modify > Timeline > Clear Keyframe (Shift+F6). Your keyframe will be removed from
the Timeline.
