Er, Aldaron, it's not. Photoshop help: "Resampling refers to changing the pixel dimensions (and therefore display size) of an image. When you downsample (or decrease the number of pixels), information is deleted from the image. When you resample up (or increase the number of pixels), new pixels are added based on color values of existing pixels. You specify an interpolation method to determine how pixels are added or deleted." The problem is especially bad when you increase the size, cause PS will add information which was not there. But if you turn the resampling off, and then change the resolution, the pixel dimensions will stay the same, but the metric (inchic :-)) dimensions will change. That way you can see how big your image will be in print, for instance. You can also change the physical dimensions, and the pixel dimensions will stay the same. You'll see the same picture on screen, but what's printed is smaller or bigger.
