Assume that I want to resize a large image (i0) into different smaller images (i1, i2, i3... where i0 > i1 > i2 > i3 ...) and keep the original ratio when doing the resize. I wonder which of the following approach will generate better result -


i0 -> i1 -> i2 -> i3
i0 -> i1, i0 -> i2, i0 -> i3


Any inputs are welcomed! Thanks!

For jpg.. there's no question that #2 is the only acceptable method. Jpg is a lossy format. Every save throws away data. Resaving a jpg as a jpg always results in a lower quality image. For this reason you should always return to the original image if you need to resave. Having an original format such as tiff, png24/32, or psd would be better. But at times jpg may be all you have.
