# Image

An image for the @boardname@ screen.

### @parent js/language

An *Image* is a matrix of pixels to show on the [LED screen](/device/screen)

### Touch Develop editor: plot an image

* click `image` , `plot image`, and then `edit`
* click the rectangles to create an image
* when you're done, click **ok** to return to your code

You should see code similar to this:

```
basic.plotImage(`
. . . . .
. # . # .
. . # . .
. # . # .
. . . . .
`)
```

### Creating an image

To create an image that you can later modify, see the [create image](/reference/images/create-image) function.

### Block editor: create and show images

To create images using the [Block editor](/blocks/editor):

1. Click the **Images** category on the left.

2. Drag and drop the **show image** block into your code.

3. Drag and drop the **create image** or **create big image** block onto the **show image** block so that they connect.

4. Make an image on the **create image** block by clicking on the squares.

### Global image variables

Images that you create in the [Touch Develop editor](/js/editor) are [local variables](/reference/variables/var). To promote a local image variable to a global variable, select the local image variable and click `promote to data`. The *var* keyword changes to the [data](/js/data) symbol `data->`.
