I'm using Paint Shop Pro. Since I posted, I have been researching this a bit and When I was resizing, I might have been trying to get to a reduced size by resizing an image that had already been reduced, instead of resizing from the original image. I have also discovered the 'preview in web browser' function which gives me a little more control over how the image will appear.
Any other pointers would be appreciated.
