What would be the most efficient way to grab a number of random pixels (RGB value) from a BufferedImage. Preferably equidistant from each other.

By "random", do you mean actually random x and y values, or just that they could be any x and y values? For the latter, check out the getRGB(int, int) method. The former could be implemented by feeding random values into the two parameters of that method, although that wouldn't address the equidistant constraint.
