```You could also use the DisplayTogether command. Or you could try the
DrawGraphics package at my web site, which makes it easy to combine various
types of graphics in one drawing statement.

Needs["DrawGraphics`DrawingMaster`"]

Draw2D[
{DensityDraw[Sin[x]Cos[y], {x, -2, 2}, {y, -2, 2}],
Red,
ParametricDraw[{Cos[t], Sin[t]}, {t, 0, 2Pi}]},
AspectRatio -> Automatic,
Frame -> True,
PlotLabel -> "Parametric Curve on a Density Plot",
Background -> Linen,
ImageSize -> 450];

Hi,
I found a method:
a=InputForm[ParametricPlot[{Cos[t],Sin[t]},{t,0,2Pi}]];
DensityPlot[Sin[x]Cos[y], {x, -?, ?}, {y, -?, ?}, Epilog ->{Hue,
a[[1,1]]}];

and I forgot to thank you in last post.  :-)
