It’s hard for me to express how much I enjoy getting e-mail messages that are two or three megabytes in size because the sender decided to take a screenshot and send it to me via Outlook. I suspect there’s some goofball setting in Windows that lets you snap a screenshot and mail it to someone, but the default format (thank you Microsoft!) is a bitmap image… which is huge because it’s 24-bit uncompressed. The exact same image, without appreciable loss of quality, might take up two percent of that size– a mere sixty kilobytes.
Ahh, clients… without them my life would be so much simpler.
