Yes Pedrith. The surface replicator that Dex mentioned does do that and more. Randomize the size/placement/angle following the geometry of any surface, with a texture (picture) based control of placement. (Place a greyscale pic in the right place, then the layout of the duplicates follows the 'brighter is more' mentality.)

When you go to the render room and pull up on the 'Current scene/Batch Queue' tab across the bottom you can add scenes (files) to the render queue and make whatever changes you want to the render settings of the file. Different resolutions, quality settings, 'Save render to file...' settings, blah, blah, blah.

What I hear from folks who do renders for print, (I usually do my work for screen or video,) that setting your render to twice the DPI of the output device, then downsampling in PhotoShop or (insert program name here) is the best bet, since it does a cleaner anti-aliasing.

Hope this helps.
