We have covered quite a few screen capture tools to take screenshots as well as record screens. ShareCapture is another free tool to capture screens, but unlike other free screen capture tools, this application can upload the image and you can share it instantly. A link to your screenshot will be ready in a seconds and you can share it any way you want.
You can press print screen, mark the area you wish to share and paste a link to where ever you want. You can set up FTP access to ShareCapture and you can set the path where the screen capture needs to be updated.
