Many image editing programs have built-in features that automatically resize and compress images for emailing. Problem is, sometimes, that the images don't look as well as if you resized them in a program such as Adobe Elements or PaintShop Pro.
Do you have any image editing programs on your computer? If so, which one?
A very good free program to resize and email images is one that I mention often: Picasa2, which will attach images to your email client automatically. The program, when used with another free program "Hello" is made specifically for photo sharing.
