Hi,

BinaryMatrix[prob_, n_Integer, m_Integer] :=
Table[If[Random[] < prob, 1, 0], {m}, {n}]


RandomImage[prob_, n_Integer, m_Integer] :=
Graphics[
Raster[BinaryMatrix[prob, n, m], {{0, 0}, {n, m}}, {0, 1},
ColorFunction -> GrayLevel], AspectRatio -> Automatic,
ImageSize -> {n, m}, PlotRangePadding -> None]

and

RandomImage[0.05,30,30]

will do what you want.

Regards
Jens
