It looks like when you "save as image", the extension for the world file that gets created is just the extension of the image type, plus a "w". So, a png becomes pngw, jpg becomes jpgw, etc. I think this is the way that GDAL works, which would explain things - but it would be nice if it used the alternate method so that it would work with things like Autocad, for example, without having to manually rename the file. A lot of software uses the other naming method where you take the first and last letter and then add a w to those. So jpg becomes jpw, tif becomes tfw, etc.

It's obviously very easy to rename manually - but like I said, it would just be a nice little change if it did this out of the box.

This is the original ArcInfo way and taking the 1st and 3rd letter from the short DOS 8.3 style filename came later with ArcView. However, the three letter world file extensions are for sure much more common.

This is QGIS specific behaviour, GDAL creates short world file extensions. Sometimes they are even named as .wld.
