well i would say tak e a look at my fla buuuttt its not letting me upload it so i shall try to explain the problem in more detail since iv read the solution on this site and know it is simple.
i have two jpgs blend into eachother using alpha settings. as in one jpg goes from 0-100 alpha and the other goes from 100-0 making them look like they morph to eachother. anyhow. in the middle of tweening part of the jpg with jitter or shake just slightly alltho all the jpgs are lined up perfectly.
-thanks
