Cathy, Yes, the pixels refer to the pixels dimensions of the image, e.g. 640 x 480, 1600 x 1200 etc. With most cameras you can select from multiple pixel dimensions for the capture of your original images. For example I use 2048 x 1536, to gibe me 3.4 megapixels, or so. The pixel dimensions have nothing to do with compression. The latter is a way of driving down the file size (and quality) whilst maintaining the pixel dimensions. Thus I can save my original 2048 x 1536 image with whatever compression I want in the jpg format, to end up with a variety of file sizes proportional to the compression. You can also independently change both the resolution (in pixels per inch or dots per inch, dpi) and the pixel dimensions of an image, for example to get an original down to the 640 x 480 format I use for web work with a resolution of 72 dpi. In this case PS resamples the pixels and cuts out a number to bring the dimensions down to the value I've chosen. Compression, pixel dimensions and resolution are completely different things but in combination determine the quality and file size of your final image. In going from the camera to the web I reduce both the file size by compression and the pixel dimensions by resizing. A jpg is just a file format made by lossy compression - it can be as much or as little compressed as you choose, depending upon your needs. J. PS. And how about comments from someone other than me - PLEASE !
