With this set, an image meant to be 5 inches wide at 300dpi will actually display as 5in wide; without this set, the image would display as approximately 15.6in wide since the image is 15000 image pixels across, and by default CSS displays 96 image pixels per inch.
The resolution and file size of your image will change when you adjust any of the settings in the Image Options section of the window. The current image has a file size of 9.3 MB (megabytes). I want to resize the image to approximately 1 MB or smaller. So I used the pull-down menu to set the resolution to Medium.Note that the file size is now 893.8 K (kilobytes), approximately 10 times smaller than the previous file.CS3 has arbitrarily removed pixels to create a smaller file.lways Make a Copy. Always, always, alwaysâ¦ always make a copy of the image that you are about to resize. In fact, you should always make a copy of your original image, even before you edit it. Then, once you're pleased with your edited image, make a copy of that before you resize it.
