Help please!

sorry guys i have 2 questions

  1. im trying to create this motion tween where i have these group of pictures in a line and i want to make them go across the screen over and over. Now i was able to do that but its not as smooth and appartly its too fast, plus whenever it restarts it kind of looks funny, i want to make it repeat continually where u dont see spaces in between? sorry if this may seem a little complicated but i need help.

  2. I was doing the shine effect based on this tutorial http://www.kirupa.com/developer/mx2004/shine.htm
    now i got it to work with text instead of shapes and im wondering how can u make the words reappear? Ive tried added new frames and stuff and it wont work. Please help me on this thanks!
