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];
