XML loading thumbnails HELP PLEASE!

1

Here is the problem :
http://phoenix68.9online.fr/daeja2.swf

since each thumbnail have different sizes i can 't scale then in the thumbnail scroller:m: :m:

here is the part of the code i d like to fix:

function thumbnails_fn(k) { 
thumbnail_mc.createEmptyMovieClip("t"+k, thumbnail_mc.getNextHighestDepth()); 
tlistener = new Object(); 
tlistener.onLoadInit = function(target_mc) { 
target_mc._y = hit_left._y+(eval("thumbnail_mc.t"+k)._height+5)*k; 
target_mc.pictureValue = k-1; 
target_mc.onRelease = function() { 
p = this.pictureValue; 
nextImage(); 
};

the prob come from this line i think :

target_mc._y = hit_left._y+(eval("thumbnail_mc.t"+k)._height+5)*k;

actually it places the movie according its own size assuming that all the previous movies in the loop where the same size. but they aren’t

here is the FLA:
