Problem with modifying xml photogallery tutorial

I want to modify this tutorial’s xml photo gallery: http://kirupa.com/developer/mx2004/xml_flash_photogallery.htm

So I change the white box in the layer “area” to the size of my pictures and switch the xml location to the name of my xml document. The problem is that it will not recognize pictures that match the new size of the white box… but it will open any picture that is bigger than the size of the box…I have no clue how to fix this. Can somebody please help me?

I can give you as much info as you need, I’ll even send the .fla if you wanna take a look. Thanks for any help.
