Although you can make an image appear smaller on a Web page than it really is (see the Sizing images in HTML section, later in this chapter), it s usually best to set the size deliberately before the image ends up on your site This is a simple process, although there are a couple of caveats When you resize an image, your graphics program has to change the pixels the color dots that make up the image Obviously, a larger image will take more pixels and a smaller one will take fewer This means either adding pixels (interpolation) or subtracting pixels (resampling) Although graphics interpolation has come a long way, any image-resizing process still has to make some compromises Shrinking an image usually doesn t damage the capability to view the picture, but it always has to mean some loss of detail Enlarging an image can add areas of blockiness due to the additional pixels needed to fill the new space The best resizing is a minor resizing Open the image you want to resize in IrfanView, and then follow these steps: 1 Choose Image Resize/Resample from the menu In the Resize/Resample Image dialog box, shown in Figure 7-8, there are three methods of setting the new image size: To specify a particular physical size, in the Set New Size panel, select pixels, centimeters, or inches, and then enter the new width and height in the Width and Height text boxes If the Preserve Aspect Ratio check box is selected, you have to enter only one of the values; the other will be automatically entered To use a percentage, select the Set New Size as Percentage of Original radio button, and then enter the appropriate numbers in the Width and Height text boxes To use common sizes, click the appropriate button or select a radio button in the Some Standard Dimensions panel 2 Click the OK button 3 Save the image If you don t save the image after you make your changes, you ll lose it
