loadmovie over prev loadmovie and positioning jpg

Hello, a little question and i have the feeling i am very close.

i use loadmovie to load an image into an movieclip.
that movieclip goes to the position x and y of the movieclip - the loaded image width/2

my problem is that when i load a new image the position is not correct.

my code:
--------------------------------------------------------------------------------------------------------------------
function nextImage1()
{
if (p < total - 1)
{
++p;
if (loaded == filesize)
{
trace(p);
trace("x van inst0"+litlimg_instance.ltlimgmc_instance0._x);
trace("y van inst0"+litlimg_instance.ltlimgmc_instance0._y);
litlimg_instance.ltlimgmc_instance0._alpha = 0;
litlimg_instance.ltlimgmc_instance0.holder.loadMovie(image

, 1);

var maxWidth = 250;
var maxHeight = 200;

var myWidth = litlimg_instance.ltlimgmc_instance0._width;
var myHeight = litlimg_instance.ltlimgmc_instance0._height;
// Calculate percentage by which image will need to change to fit
if (myWidth > maxWidth){
var xscalePercent = (myWidth*100)/maxWidth;
}
if (myHeight > maxHeight){
var yscalePercent = (myHeight*100)/maxHeight;
}
// Multiply both height and width by the bigger percentage
if (xscalePercent>yscalePercent) {
litlimg_instance.ltlimgmc_instance0._width /= (xscalePercent/100);
litlimg_instance.ltlimgmc_instance0._height /= (xscalePercent/100);
} else {
litlimg_instance.ltlimgmc_instance0._width /= (yscalePercent/100);
litlimg_instance.ltlimgmc_instance0._height /= (yscalePercent/100);
}
var test=litlimg_instance._x-(litlimg_instance.ltlimgmc_instance0._width/2);
trace("width img:"+litlimg_instance.ltlimgmc_instance0._width);
trace("width:2 :"+litlimg_instance.ltlimgmc_instance0._width/2);
trace("x position must be:"+test);
trace("x position is:"+litlimg_instance.ltlimgmc_instance0._x);
trace("----------------------------------------------------");

litlimg_instance.ltlimgmc_instance0._x=litlimg_instance._x-(litlimg_instance.ltlimgmc_instance0._width/2);
litlimg_instance.ltlimgmc_instance0._y=litlimg_instance._y-(litlimg_instance.ltlimgmc_instance0._height/2);
slideshow();
} // end if
} // end if
} // End of the function


function slideshow()
{
function pause_slideshow()
{
clearInterval(myInterval);
if (p == total - 1)
{
p = 0;
firstImage1();
}
else
{
nextImage1();
} // end else if
} // End of the function
myInterval = setInterval(pause_slideshow, 4000);
} // End of the function

p = 0;
--------------------------------------------------------------------------------------------------------------------

what i do is i have an array with the image links.
on a interval i load an image. and if p has reached the number of loaded images i start over again.

i traced the following while testing a bunch of images:
-------

1
x van inst0-125
y van inst0-93.55
width img:250
width:2 :125
x position must be:-125
x position is:-125
----------------------------------------------------
2
x van inst0-125
y van inst0-93.55
width img:258.05
width :2 :129.025
x position must be:-129.025
x position is:-125
----------------------------------------------------
3
x van inst0-129
y van inst0-93.55
width img:140.3
width :2 :70.15
x position must be:-70.15
x position is:-129
----------------------------------------------------
4
x van inst0-70.15
y van inst0-93.55
width img:243.2
width :2 :121.6
x position must be:-121.6
x position is:-70.15
----------------------------------------------------
1
x van inst0-125
y van inst0-93.55
width img:250
width :2 :125
x position must be:-125
x position is:-125
----------------------------------------------------

It looks like he takes the position of the prev image or something like that.

Please some help here.

Ps: this was some code i posted.. i would like to know how you put it into such a nice code block on the forum so it becomes more readable.
