I tried reducing 1% 3 times (so reducing the reduced reduced file), it seems to bottom out at 275/276kb (different name each time, so can keep track of them, and the original).
In case I got my % the wrong way round, I tried 99% which did about as much as a straight through 14-18t 5 speed freewheel!
Mystified!

A reduction to one-hundredth of the original image size should not be needed unless your original image was HUUUUUGE!

I think you're probably saving the image in an un-compressed format. Don't save as a BMP, save as a JPEG.

It is a .jpg file, started off as 3.28MB. It gets to 275kb, but further reduction has no effect (I think because the "dimension" is 1x2, so goes no smaller).
I reduced by %, not by pixels, would reducing by pixels make any difference?

I can't imagine that reducing by pixels is going to make any difference but so long as you keep the original and save the reduced copies under different file names you've nothing to lose by trying.
It's got nothing to do with vorsprung durch technic you know ...
