Alright! New version! This version now displays a progress bar while rendering, which also allows the user to cancel the rendering by pressing the ESC key. It also now has support for frame padding, of which the number can be easily controlled with the nFramePadLength variable. The last change is that it will also render in any selected image format from the render globals, not just iff!

Hope you guys enjoy!
