If you have aquired the OS streetview data set and you want to use then
in qgis then you will ned to create world files in order import the tiles
correctly into your vector layers.  This script copies and renames the
relevent files into the same directory as the tiff files and so enables correct
tiling in gqis
Rename files in a folder and copy to new folder.
Specifically for OS files for use with qgis.
The DEST_DIR needs to be changed to suit your file set before running the script.
