I have around 400 images that are taken from a 8 megapixel camera. I want to reduce the image size to around 4k pixels. What is the fastest way to do this, I have access to both windows and linux systems.

Really only 4k pixels? Anyway, using GraphicsMagick you can run:
gm mogrify -output-directory 4k -resize 52x78 *.jpg
Or, if you prefer, ImageMagick has pretty much the same syntax.
Irfanview. Does it all and it's free.

Yes, Irfanview would be my choice for this job on Windows machine. The gui interface to specify this batch job makes its slightly easier than using command line.– sabre23tNov 4, 2010 at 10:59

Ya, that's what's great about Irfanview. Has a batch processing mode with a ton of options. In fact, batch processing is really all I use it for. Nov 4, 2010 at 15:27
