Problem with the photo gallery tutorial

Why is the picture not centering in the stage in this tutorial eventhough I setted the movie clip in the center?

It has something to do with the registration points of your movieclip, I believe it’s suppose to be in the upper left hand corner or one of those corners, I forgot. If you can’t get it then post your file and I’ll see if I can fix it for you. =)

The upper left hand corner of the image you are loading attaches itself to the registration point of the clip you are loading to.

What I do for loading things in is create an empty movie clip and position that where I want the upper left corner of my image to be, then load to that clip.

Thanks for the replies! I’ll just post again when I have problems!=)
