Lightbox "fancybox" issue

Hi there,
i have an issues with the fancybox option, when opening an image that belongs to a gallery in an album, that the image floats left when opened.
That doesn’t happens when opening an image from an gallery that isn’t child to an album.

Hope to ear from you. If any example required please ask for me to reply this again. Thanks in advance.
