Logo on top of slideshow

[Sampie]

Hi all,

I'm building a site in Xara Web Designer MX Premium and I am facing a problem:
I've put a logo on top of a slideshow, but every time the photo slides the logo is overlapped (see picture attached), even though I've put the logo in front.
Is there a way to prevent this happening?

Hope someone can help me out.

Best regards,

Sandra
