GDAL2Tiles Project
The GDAL2Tiles open-source project allows easy publishing of raster maps on the Internet. Your raster file (like TIFF/GeoTIFF, MrSID, ECW, JPEG2000, JPEG, PNG) is converted into a directory structure of small map tiles (TMS compatible), which you can just copy to the webserver. Simple webpages with viewers based on Google Maps and OpenLayers are generated as well - so anybody can comfortably explore your maps on-line and you do not need to install or configure any special software (like mapserver) and the map displays very fast in the webbrowser.GDAL2Tiles can prepare the supplied maps for displaying in Google Earth (with KML SuperOverlay).
World files and embeded georeference is used during tile generation, but you can publish a picture without proper georeference too.
An updated open-source project with graphical user interface and support for Google Maps Overlay tiles is available at:
AN EXTREMELY FAST PARALELLIZED VERSION SUITABLE FOR LARGE DATASETS IS AVAILABLE AT:
Look at the Grand Canyon USGS DRG map or the Great Britain OpenData processed with MapTiler/GDAL2Tiles.
