Don't annoy your friends and family!

When posting photos online, you do not need nearly as many pixels as you do for printing. Having too many pixels makes it difficult to view photos on a monitor and it makes the file size much larger--something you need to avoid when posting photos on the Web or sending them by email. Remember, not everyone has a high speed Internet connection or a large monitor, so sizing photos down before sharing them is the courteous thing to do.

If you want your friends and family to smile instead of frown when they see your new digital photos, follow the guidelines in these two articles to make your pictures smaller for sharing online.
