Image thread dimension

What should the dimensions be for an imagine-thread. I ve seen some threads like this , they dont type in the epvp thread , instead they upload an image with whats needed to be said about the thread and this way you can have some nice looking visuals on your thread etc.

Its just depends on you, but its important to get everything on it
730x1600 should be the standard.
765 pixel is the maximum width and the length got not limit, but I wouldnt go over 3000 pixel.
There are many thread designer at the black market, so you could just buy a design.

End of all: Your own choice.
