Make pop up window to the Adding Thumbnails tutorial

Hi… I wanted to know if its exist some way to make a pop up window to the Adding Thumbnails tutorial. What i want to do is a click on the empty movie clip, and made from this a pop up window who refered to the root of images in the xml archive.

I put on practice the Adding Thumbnails tutorial:

go to “entrar” then click to the link “galerias” and see how i put it on practice…

And i think its look great when one of us could use the great information of this site to make our ideas work.

The only thing i couldnt do, is adjust the first thumbnail image to the movie clip who contains all the images. I could modify the space between the thumbnail images, but i cant make them start at the left margin when its loads for the first time.

If someone has some idea of how to make a pop up window who refered to the empty movie clip and from the data contained in a xml archive, and to make the first thumbnail image to load at the left margin from the begin, i would apreciate your help.

sorry if my english is not good, i hope you understand what i supposed to say.
