A sort of image selector

Inspired by a video found on the web, i'd like to make a simple image selector, in this way:

This is the starting image:

So you can see only 5 of X images, at the center the image is more bigger. Now if you click on the RIGHT ARROW this is the result:

So now the 2 is at the center, the second image is 3 etc.

I have try to make an attempt but i have some problem, i don't know how to create the GUICtrlCreatePic stored in an array based on the number/names of images (obv the images has different names, not 1-2-3 ) and move it left-right, maybe with some nice fade effect if possible

On attachment the image and my starting au3 script, thanks for any type of help
