On Windows, I was spoilt by the fantastic Greenshot, a superb (and free) screenshot tool that had among its many features, uploading to Imgur.com.
I currently use CloudApp but I've reached my 'limit' for uploads and I don't feel like paying for their Pro service when there's myriad of free (and better) image hosting services like Imgur etc.
So are there any screenshot apps which can plug into Imgur?
