ScreenSend allows you to quickly and easily show someone something on your screen. It eliminates many of the steps normally associated with doing this, and takes e-mail attachments out of the equation. By choosing "Screenshot" from ScreenSend's menu, you can select an area of the screen, give it a URL, and it uploads immediately. Your screenshot is now hosted on a dedicated server at a datacenter, and is accessible from anywhere on the Internet.
With ScreenSend you don't need to worry about whether or not your computer can host the image for others to see. Many home networks today are protected by firewalls or routers which block incoming traffic. ScreenSend hosts your screenshots on an outside server, not your own computer. As a general rule, if you can get to the web, you can post your screenshots via ScreenSend.
