Why should I avoid using e-mail attachments?

• Primary vector for viruses
• Time-consuming:  Recipients have no choice once they retrieve mail, but must endure the wait.
  • With a dial-up connection, assume about 10 megabytes (MB) per hour download 
  • Regular digital photo files usually range from 1 to 4 MB each (at 3 to 10 megapixels)
    • Megapixel calculators (Peter Forret)
• Some recipients automatically block attachments, or won't open them
• Large attachments can overfill a mailbox and prevent the owner from getting e-mail
• Limited file sizes
  • Most Internet providers allow maximums of 3 to 8 MB
• Subscriber-based e-mail mailing list groups often reject attachments
• You can't change your recipient's file copy once you've sent it as an attachment (you can with a web folder)
