If you use wget recursive download,
the images that will get downloaded may need to be the actual link.
I'm not using myspace and can't give it a try.
So I guess the picture album may use some javascript code to display
picture.
Then wget may not be able to download them.
I'm not sure there is a work-around or not.
Maybe you can contact myspace.com to see if there is a solution for
you.
