Try this: on a higher level, create a rectangle the same size as the image.


Then create a linear gradient that goes from the background color at 100% 

alpha to the background color at 0% alpha and apply it to the rectangle. 

Delete the outline if there is one.


Copy the gradient-filled rectangle and use editPaste Place. Use 

Modify->transform->flip horizontal, then select the arrow tool, select the 

copy of the rectangle (which will be all you can see) and slide it over 

until it just meets one edge of the first rectangle. If you've moved it in 

the right direction, you'll now have a rectangle twice as wide as the image 

that goes from transparent to background color back to transparent. 

Actually it's two rectangles, but select them both, group them, and make 

them a symbol (F8).


Move the whole symbol so it just touches the left edge of the image. Create 

a keyframe a number of frames down the timeline. In that keyframe, move the 

double-rectangle symbol so it just touches the right edge of the symbol. 

Apply a motion tween to the frames in between.  That should do it.
