MyImgur is a tool to quickly upload pictures to Imgur.com, is able to send multiple files in a queue, crop an area of the screen, clipboard, or capture the active window (by default F11). Once uploaded, the program can copy a link to the file directly to your clipboard.
The program can also auto-resize pictures and/or lower quality automatically if file exceeds a given size to speed-up uploads on slow connections. Captures can be stored from cropping or paste and supports multiple monitors in any configurations (spanned horz/vertically etc.).
Functional in Linux via Wine.
