Space images in Horizontal scroll

Question

Being new to AS and Flash 8 I am using an online tutorial as a guide to the creation of a horizontal mouse driven scrolling gallery.
I was hoping to use the model script and make simple adjustments of file names and loading specs but it has gone beyond my simple understanding.
I have 64 images which need to load 50 pixels apart starting with a 50 pixels pace. The image sequence will loop. Each image is of constant 385 pixels deep but widths vary and I hoped AS could load them in sequence at 100% instead of using a finite number for the width. The attached file shows the gallery images at bottom right, loaded but all stacked upon each other with the last image uppermost.
Code so far:
this.createEmptyMovieClip("container",1);
var imagesNumber:Number = 64;
var baseX:Number = 0;
var spacing:Number = 50;
for (i=1; i<=imagesNumber; i++) {
container.attachMovie("image"+i,"image"+i+_mc,i);
myImage_mc = container["image"+i+_mc];
myImage_mc._x = baseX
myImage_mc._y = (Stage.height == myImage_mc.height);
baseX = baseX + myImage_mc._width + spacing
Once I get the loading process correct I think I can revert to the tutorial model for the rest of the AS.
Can anyone help please?

Thank you both for the response guys.
The code above is part of a tutorial describing the AS to create a mouse driven scrollable gallery. The tute uses thumbs and clicks to a larger image window from each thumb. I simply wanted to create a gallery of images straight out of the fla Library to a standard height. I figured the exercise would allow me to engage constructively with AS in a real project. the code is only the first part of the tute project. I changed the code image names to suit my files and the fact that the model has thumbs and images suggests I may have rendered some code unusable or redundant and caused a malfunction in the Test. Yup, I am trying to run before I can walk and the points you guys have made illustrate the need for me to assemble specific code models instead of trying to adapt code at this stage when I know so little.
I want to sincerely thank you guys for your helpful responses. I shall check out each code element again in the light of your observations. I very much appreciate your detailed observations.
