Find the "re-size image" toolbox to change the resolution of your photo. Change this number to the highest possible number of pixels. For instance, a quality 8-by-10-inch print is usually 300 DPI (dots per inch). Most software programs allow you to choose number of DPI for that particular photo. Remember, the higher resolution mean better quality that gives you opportunity to increase the size of the photo and maintain sharpness.

Step 4

Check the resolution of the photo before downloading from your camera or scanning to your computer. If the photo isn't high-resolution you can't add pixels to improve the image's quality. But if an image is high-resolution (300 DPI or higher), you can remove pixels to reduce file size or edit for blemishes or scratches. You can only change resolution if you have enough DPI in your image to work with.
