Slideshow funktion in Scottys Gallery - How?

Hi

I am trying to fintune my webpage www.apneaimages.com under PHOTOGRAPHY and i like to have 2 funktions

  1. Slideshow button. I like that the slideshow continoue from the actual picture and not start from the beggining. them I like to have a endless loop

  2. To show the pictures I use nummeric buttons and a prev & next button.
    Now, when I push the nummeric buttons they change colors and saty blue, so that the viewer know wich Picture he have see.
    But this funktion is not working when I use the Next & Prev buttons.
    Is there any chance to fix this?

Her some code:

Prev & next Button

stop();
gallery_xml.load("apnea.xml");
prevb.onRelease = function() {
 if (cur == 0) {
  containerMC.loadPic(pArray.length-1);
 } else {
  containerMC.loadPic(cur-1);
 }
};
nextb.onRelease  = function() {
 clearInterval(interval);
 if (cur == pArray.length-1) {
  containerMC.loadPic(0);
  } else {
  containerMC.loadPic(cur+1);
 
 }
};

Nummeric Button (button number 01)

 
on (rollOver) {
 this.gotoAndStop("over");
}
on (rollOut) {
  this.gotoAndStop("up");
 }
on (release) {
 this.gotoAndStop("down");
 _root.containerMC.loadPic(1);
}


Thanks Lambis
