Include an image in title page using powerdot

Question

I want to include an image at the center of the title page of my powerdot presentation. Incidentally, I want the same image to appear as a logo on all the other slides (positioned bottom centre), except on the title page. How do I achieve this? So far I did the following, which did not work:

     \title{Hardware Evaluation}
     \author{\bf{Priya} }
     \titlegraphic{\includegraphics[scale=1.0]{Logo.eps}}

    \pdsetup{
    palette=Sea,
    randomdots,
    dprop={dotstyle=ocircle,linewidth=.01pt},
    dmindots=5,dmaxdots=5,
    dminsize=100pt,dmaxsize=200pt,
    dbright=50,
    logohook=c,
    logopos={.500\slidewidth,.060\slideheight},
    logocmd={\includegraphics[scale=.03]{Logo.eps}}
   }

Can someone help me place Logo.eps as a centre image on the title slide and as a logo (bottom centre) on the remainder slides. Thank You.
