TinyGrab
TinyGrab is a simple screenshot sharing tool for Windows, Mac and iOS. The tool allows the user to take a screenshot and automatically upload it to their servers. The URL is passed directly to the user's clipboard allowing them to paste the link in an email, blog post, on Twitter, or any instant messaging application. The service is tiered with the free accounts limited to ten "grabs" a day and paid accounts giving unlimited grabs and the ability to use File Transfer Protocol to upload to custom servers.
