# Create Big Image Make a big [image](/reference/images/image) (picture) for the @boardname@ [LED screen](/device/screen). The big image made of two squares. Each of the squares is five LEDs on a side, like a regular image. ```sig images.createBigImage(` . . # . . . . # . . . # # # . . . # . . # . # . # # . # . # . . # . . . # # # . . . # . . . . # . . `); ``` ### Parameters * ``leds`` is a [string](/types/string) that says which LEDs on the screen should be on and which should be off. ### Example: Flip-flopping arrow This program makes a big image with a picture of an arrow pointing up, and an arrow pointing down. If you press button `A`, the program will show the arrow pointing up, which starts `0` LEDs from the left in the big image. If you press button `B`, the program will show the arrow pointing down, which starts `5` LEDs from the left. ```blocks let arrows = images.createBigImage(` . . # . . . . # . . . # # # . . . # . . # . # . # # . # . # . . # . . . # # # . . . # . . . . # . . `); input.onButtonPressed(Button.A, () => { arrows.showImage(0); }); input.onButtonPressed(Button.B, () => { arrows.showImage(5); }); ``` ### See also [Getting Started](/getting-started), [image](/reference/images/image), [create image](/reference/images/create-image), [show image](/reference/images/show-image), [scroll image](/reference/images/scroll-image), [show animation](/reference/basic/show-animation)
