Not Versed in Flash terms: Button loading external imgs problem

[kinda86]

Hi... I tried looking around the site for something to solve my problem but wasn't able to find anything...

I've got an image gallery (http://www.artengine.ca/cgervais/ click on the gallery button and any of the top titles) and right now it's set up so that the images are within the .fla file and the thumbnails on a different movieClip calls on each labeled frame in another movieClip which has the corresponding image. I want to recreate the file so that the thumbnails call on the different images from an external folder...

the issues I am facing with this right now are:

1) I onlly know how to set it up for a "back" and "next botton with actionscript (2.0) as followes:


var slideInfo:LoadVars = new LoadVars();
slideInfo.load("BLOCKS/photogal/slideInfo.txt")

_level0.theMCL.loadClip("BLOCKS/photogal/img" + curImgNum + ".jpg", this.img_mc);
_level0.theLV.load("BLOCKS/photogal/img" + curImgNum + ".txt", this.bio_txt);

//--------------Next BTN--------------

nextBTN.onRelease = function(){
if(curImgNum < Number (slideInfo.totalImgs)){
curImgNum ++;
} else {
curImgNum =1;
}
loadFrame();
}



//-------------------BACK btn------------------

backBTN.onRelease = function(){
if(curImgNum ==1){
curImgNum = Number (slideInfo.totalImgs);
}else {
curImgNum --;
}
loadFrame();
}


//---------functionIMGnTXT----------------

function loadFrame(){
_level0.theMCL.loadClip("BLOCKS/photogal/img" + curImgNum + ".jpg", this.img_mc);
bio_txt.scroll=1;
_level0.theLV.load("BLOCKS/photogal/img" + curImgNum + ".txt", this.bio_txt);

}

//-------------SCROLL--------------------

scrollUP.onPress = function (){
bio_txt.scroll -=1;

}

scrollDOWN.onPress = function(){
bio_txt.scroll +=1;
}
I don't know how to make it so that each individual button calls on the specific image to pop up...

2) the images are not the same size so when i was playing around with the code above the location of vetical and horizontal images are not centered on the stage and are not the right size within the movie clip...

[countersweet]

you can create some movie clip that would be still in middle and you could load the images dynamicaly from different location into that one?

for centering you need a movie clip loader so you know what the size of the image is, let me give you an example of how does movieclip loader work



this.createEmptyMovieClip("photo",this.getNextHighestDepth());
photo.createEmptyMovieClip("holder",photo.getNextHighestDepth());

mcl = new MovieClipLoader();

listener = new Object();
listener.onLoadInit = function(target_mc:MovieClip) {
photo.holder._x=Stage.width/2-photo.holder._width/2;
photo.holder._y=Stage.height/2-photo.holder._height/2;
}

mcl.addListener(listener);
mcl.loadClip(your url here,photo.holder);
