Therefore a "300px" image should have the same physical dimensions (as That's not my understanding. My understanding is that a pixel is a real pixel at typical CRT resolutions (so that bit mapped images align on pixels) but is based on a arbitrary number of pixels per inch on high resolution mediums. The resolution used to be 72dpi, but is drifting up towards the 120dpi that is the nominal resolution of 1024 x 768 CRTs. The idea being that low resolutions don't produce additional quantisation errors when handling bit-mapped images, and allow sizes to be implied by the image, and that high resolutions produce a similar layout to that on the screen (it would be better for people to use @media groups to give precise sizes for printed images, but few will).
