If you're going to share your photos via e-mail, it's a good idea to re-size them before you send them. Digital cameras can create very large image files, and these files can take a long time to download. To reduce the size of your pictures, open them in your photo editing software. Make the files smaller in one of two ways:
- Reduce the resolution, measured in dots per inch (DPI). The minimum resolution for good-quality onscreen viewing is 72 DPI.
- Reduce the image size, measured in inches, centimeters or pixels. A 3 by 5 inch (7.6 by 12.7 centimeter) picture will travel well by e-mail but will still be big enough to see.
Save the result as a new file, and keep your original high-resolution image.
If you'd rather share your photos in an online gallery than via e-mail, you can start an account on an image-sharing site like Flickr, Fotki or Snapfish. Your camera's software may also include automatic uploading options. Many of these services are free, but some limit how many pictures you can upload per month or how much disc space you can use. CNET has a good comparison of online sharing and printing sites.
