Ok check out the attached file, its extremely small (4 files). Basically, actionscript on that one layer, a mask, the 5 photos (contained within 1 MC, represented by plain colors for now) and two buttons to control left or right slide.
Please check it out, it works! Then, if you click either button really fast you’ll notice it messes up. The sliding messes up, each photo (225px width) doesnt slide 225px each time.
Thanks for the help.
