Thanks for the replies.
I used to use PS, but discontinued renting it when I gave up creating new
images some months ago. I am now using Irfanview, which doesn't seem
to have a quality adjuster, only physical size. Oh Dear, what a dill, I've
just remembered the slider I used to use in PS, [Marc mentioning a slider
brought it back to me]. I do have an old version of PS on my other laptop, so I'll have to transfer my images to that one, unless there is other software
that I can download to make it easier for me. I apologise for wasting your time, and can only use my appalling memory, and advancing age as excuses.
