Windows: Ybex Clipboard is a clipboard and screenshot tool with an emphasis on sharing with a remote computer. Snap, annotate, and share screenshots with the included free image hosting or shuttle your clipboard contents to another computer with ease.
Ybex Clipboard has two primary features. You can easily capture your screen, annotate it with text and drawings, and then share it through the Ybex server—after uploading the image it automatically dumps the URL into your clipboard. Alternately, you can share your clipboard with a remote computer with the Remote Copy/Paste feature.
Ybex Clipboard is freeware, Windows only. For another text and screenshot sharing tool, check out previously reviewed ZScreen.
