My maps georeference just fine in QGIS and I save them to jpg with jpgw. The jpg image loads but the jpgw file does not. I keep getting the error message "this is an unsupported file", or words to that effect. I have tried bmp and bmpw, tif and tifw and tiff and tiffw with the exact same result.
I got the same result with Global Mapper but surprisingly, OK Maps loaded both the image file and the world file perfectly. My GPS receiver tracks accurately with OK maps also.
Please help any way you can. I really enjoy using QGIS.
