Sorry for being noob, I'm sure there's already a known way to do this or an addon which does, but I don't know where to look.
I want to know how you can fade the bottom part of a pic so it eventually changes into one complete color, you know so I can use a picture as a youtube background without repeating it ? sorry if i'm not explaining what I mean very well. could somebody please let me know how this is done?
What I mean is something like this: http://markmichalowski.co.uk/image/blue_rust%20fading%20to%20black.jpg , if you notice the bottom it's fading into black, but i would like to do this to pictures so it slowly faces into complete darkness, or any color really. thanks so much for your time paint experts
