Sharex allows a user to take screenshots easily and upload them automatically to the service of their choosing. Combined with Tzlime you can have a speedy image upload service that you can trust not to share your data!
By simply pressing a key combination that you set, for example [Ctrl] + [Alt] + C and dragging over the area of your screen that you want to share, Sharex will upload the screencap to the website of your choosing.
