# Create Image
Make an [image](/reference/images/image) (picture) for the @boardname@
[LED screen](/device/screen).
```sig
images.createImage(`
. . # . .
. # # # .
# # # # #
. # # # .
. . # . .
`)
```
### 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
If you press button `A`, this program will make a picture of an
arrow and show it on the LED screen. If you press button `B`, the
program will show a picture of the arrow upside-down.
```blocks
input.onButtonPressed(Button.A, () => {
images.createImage(`
. . # . .
. # # # .
# . # . #
. . # . .
. . # . .
`).showImage(0);
});
input.onButtonPressed(Button.B, () => {
images.createImage(`
. . # . .
. . # . .
# . # . #
. # # # .
. . # . .
`).showImage(0);
});
```
