do you mean cropping an image? resizing a picture innately means that you ARE changing the pixel resolution, while cropping referrs to cutting part of the picture from the original in order to make it smaller.



Pixels (short for picture elements) are the smallest displayable information of a digital image. if your document is say, 500px by 500 px, you cannot make it larger without causing some ';pixelation'; or noise. This is because photoshop is trying to create new pixels out of the opnes that currently exist. It's usually a muddied combination of the original pxel colors around it. The general rule is that you can scale an image up about 20% before you ruun into trouble.



The one thing that will make it change size is changing the resolution. this means that this 500 by 500 px image will still have all the elements, but be displayed at a different size. web resolution is generally 72px/inch, while printed images are 300 px/inch. this means your 500px image would be about 6 or 7 inches on screen, less than 2 inches printed.



If you're asking how to keep the image at the same pixel size (say 500 by 500px) and change the resolution, make sure ';resample image'; is unchecked, then simply chane the resolution.How do you resize an image without resizing the pixels in Photoshop CS2?
Basically, resizing a digital image MEANS resizing the pixels. In otherwords, you cant increase the resolution of the image, since NO software can create data that wasn't IN the image in the first place.



One can REDUCE the resolution, but not increase it.



So resizing an image means that the pixels must be changed.



By the way, selecting ';points'; only changed the unit of measurement. Like changing from ';inches'; to ';milimeters.';
