Slider image sizes

[James Appleton]

What is the optimal image height/width to decrease the overall height of the slider? My client doesn’t like that the slider takes up the entire window height.

Hey James, best image ratio is 0,45. recommend resolution is a width of 5120px to cover up to 5k displays. concrete5 cms will automatically generate multiple versions in smaller sizes to decrease bandwith.
