Include an image in title page using powerdot

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.
