We recommend using 1800 x 600 (i.e. an aspect ratio of 3:1).
That said, there is no hard limit or required proportions for these images, so some general rules to follow for optimal display are to ensure:
a minimum width of 1800px (to guarantee sufficient resolution)
an aspect ratio between 3:1 and 2:1 (i.e. landscape photos at least twice as wide as they are high, and not more than three times as wide as they are high)
