This does what you want:

Load the continuous statistical distributions package (have a look in the
Help Browser for documentation):

<<Statistics`ContinuousDistributions`

Set up a Laplace PDF:

mu=0;
beta=1;
pdf=LaplaceDistribution[mu,beta];

Generate an image with independent Laplace distributed pixel values:

image=RandomArray[pdf,{8,8}];

Have a look at the image:

ListDensityPlot[image];
