Stamping filename on images

[Jobos]

I've got 200 photos that I want to stamp with the filename directly onto the image. I've looked at Photoshop CS3 and IrfanView but I can’t see a way to achieve this. Any ideas?

in imagemagik:

for f in [0-9]*.jpg; do fn=${f%.*}; convert ${fn}.jpg -fill black -gravity South -pointsize 30 -annotate +0+5 "${fn}" ${fn}_annotated.jpg ;done

Photoshop should be able to via its batch feature.... Just I don't have a copy here to test with to work it out.
