photo mosaics

I’m assuming that, by Photo Mosaic, you mean one image mad up of hundreds of smaller images.

In Photoshop, there’s no easy way to do that. However, Roxio’s Photoshite 4 (and later) has the capibility to do this. It’s only a $50 program, so with the time you would save by doing everything manually in Photoshop, the Roxio option would have paid for itself 10X over.

If you’re a member of NAPP you can get a free mosaic plugin from AutoFX.

AFAIK there is no photoshop filters for photomosaic.
but there are programs that could generate them.
some of them freeware some shareware so in any case you may try them for free.
