Try the following and you will be amazed. Install the ImageMagick. Create a new batch file (with the extension .bat) on your desktop. Edit it and add the following text:
Code:
convert %1 -depth 16 -filter Mitchell -gamma 0.4545455 -resize 200%% -gamma 2.2 "%~n1_IM_200_pct.tif"
Drag and drop any tif file you want to resize onto this icon. The batchfile will then resize your image to 200% and output a new 16-bit tif file with the addition of _IM_200_pct to the original file name. It will create this new file in the same directory as the original image which is dragged and dropped. The resizing works in the 16 bit domain making use of a gamma of 1. The output may need a slight sharpening which you can do in your favorite program.
PS: The idea of using batchfiles with ImageMagick like this is of course courtesy of Bart. You can also create this batch file in the Send To folder so that you can right-click on any file and execute the action.
PS2: You can also use QImage to uprezz even if you are not printing. Just choose the output type "file" and create a upsized document using an imaginary printer size with an imaginary ppi (together resulting in the required final image dimensions in pixels).

Hi Cem,
Thanks for the above. I use the Send To option quite a bit - it works very well with ExifTool.
I realise that QI can be used without printing, but it gives me a headache struggling through the maze of menus :-(
BTW, Irfan View has the option to use Lanczos, and FSIV has both Lanczos and Mitchell.
I've installed IM, but so far it crashes with everything I give to it. I've got a couple of old programs that need to be run as Administrator in Win 7, but that didn't help. I'll keep trying; my brain needs a bit of exercise!
Regards,
Stuart
