Once you have opened the file
"picturemove_user.fla" that you downloaded, you will see the cloud image that
I used. Right click on the clouds and select Edit in Place.
We will have to animate the clouds image to
make it look like it is scrolling left to right. Insert a keyframe on Frame
500 of your timeline. Now, while your animation is on Frame 500, select the
clouds image and press SHIFT + Left arrow until the very right corner of the
image matches the right corner of the movie stage:
Now, highlight all the frames between Frame 1 and Frame 500.
While the frames are highlighted, right click on any highlighted frame and
select 'Create Motion Tween'. The image will now be tweened. When you preview
the animation, you will see the clouds moving across the screen...albeit
slowly.
Now comes the task of formatting the image to make it look half-way
decent. Select the first keyframe and click the cloud image. Go to the Effect
panel and select Alpha from the drop-down menu. Enter a value of 5% on the
text field on the right.
Now, select Frame 500 (which houses another keyframe) and select the cloud
image again. Alpha the image to a value of 5% just like you did for the
instance of the image in Frame 1. You should barely be able to see the the
image of the clouds at this point.
Now, right click on Frame 100 and select Insert Keyframe. Select the cloud
image and set the Alpha to 50%. Insert another keyframe on Frame 400 and set
the Alpha of the image to 50% as well.
When you preview the animation, you will see a
good scrolling effect with the illusion of actual clouds moving. This effect is
not bad considering the size of the completed animation is only around 15-20k.
If you post on my forums, you will see this same effect on my footer. My entire
footer with this effect, text, and randomly moving objects is only 8k. Click here to see how my footer looks like.
