Where's "nextgen-gallery/view/gallery.php" in NextGEN 2.0???

I have updated the plugin and now all the links of my images of NextGEN Gallery 2.0 to a post in web are broken. I have been always following this simple process:

BUT NOW I CAN’T FIND GALLERY.PHP!!!!

?How can I link the images to my custom field called “Link” and NOT TO THE IMAGE URL????
