Gdal_translate program has options for you:
Usage: gdal_translate [--help-general]
       [-ot {Byte/Int16/UInt16/UInt32/Int32/Float32/Float64/
             CInt16/CInt32/CFloat32/CFloat64}] [-strict]
       [-of format] [-b band] [-outsize xsize[%] ysize[%]]
       [-scale [src_min src_max [dst_min dst_max]]]
       [-srcwin xoff yoff xsize ysize] [-projwin ulx uly lrx lry]
       [-a_srs srs_def] [-a_ullr ulx uly lrx lry] [-a_nodata value]
       [-gcp pixel line easting northing [elevation]]*
       [-mo "META-TAG=VALUE"]* [-quiet] [-sds]
       [-co "NAME=VALUE"]*
       src_dataset dst_dataset
By playing with -srcwin or possibly with -outsize and -projwin you should be able to split your image as you wish.  Read more from

	Aihe: [mapserver-users] How to tile a large TIF image?
	Hi there, 

	I would like to use instead of single large tif image smaller tiles. Although I am well aware of mapserver's and gdal's possibilities to create the shapes for it, I first need to "split" the large tif into 20 or 50 or 100 tiles.

	Can anyone give me a hint with what kind of software this is possible? 

	There is an ArcGIS script, but it doesn't work on my machine ( http://arcscripts.esri.com/details.asp?dbid=13978 ).

	Thanks for any hints,
