Exactly!! wow fantastic scene!! is it easy to do? and wont take years to render ? hehe im new to this and this is my second all poser in poser no adding stuff outside of poser work..

Do them in layers, with only a few people each layer. Save the renders in PNG format, so the background will be transparent. Then composite them in Photoshop (or whatever graphics program you use).

Either png or tiff will work to save your characters against a grey background. In PS, go to Layer -> New -> Layer from Background. Then go to Select -> Load Selection and pick the Alpha 0 layer and click invert. This will select the background color and you can simply delete it. Then use the move tool to place the figures on your background. Once you have all your figures placed in the scene, you can do things like shadow effects by copying a layer and putting its threshold value at the max. The transform tools can then be used to position the shadow on the floor. And then lower the opacity of the shadow so that it fits with the image. To add depth once you have all your shadows in place, merge everything down. Then create a duplicate layer and use the find edges filter. Change the effect of the layer from normal to soft light and reduce the opacity from 10 to 20%. Then create another duplicate layer from the original layer. In your droplets, select either old photo or oil paint. Then change the layer effect to soft light and reduce the opacity down to 30 to 60%. Merge all of your layers down. Hope this helps :)

If the crowds are distant, or smaller sized (for example small enough to walk through the archways on either side), you can use low-resolution characters.

His approach was to render a row of people, then turn them into a 2D texture with transmap that can then be applied as a map on a simple square prop. Very low memory demands and allows you to composite within Poser.

...of course, they do get very very skinny in profile....

I hope it is okay to mention :) I have two Nude P4 figures in the Market Place that with the body morphs, scaling and face morphs make a huge variety of figure for a scene. I pose them, dress them in P4 standard clothes scaled as needed, export them with the clothes as .obj files and import them back in as a static prop... this way the render overhead is low but I can move the camera around and have them look right since they are true geometry and at render the shadows are right since everything is in the scene at once. Figure groups can also be saved as .obj. You loose the transperency setting you might have but I think for "mass" render like this it is good to remove all textures and use surface color only, the clothes can be textured after the fact in an editing program, just noise usually works but I have tiny cloth textures I apply with the Photoshop pattern brush. There is a product called AZL crowd Kit (I think) but it is pre-made figure groups mapped and transmappeded on a flat plane. There is something called RMW: Crowds and Army Generator 01 but I have no real idea how it works. It seems as though it is an aid in rendering large groups of figures and compositing them on transmaped planes but I could be totaly wrong about that.

Wow thank you all for your help i'll be working on this today!! (I use psp8 not ps lol it doesnt like me) *bookmarks and runs off to make little ppl)
