# Image

SpinaCMS uses ActiveStorage to handle image uploads and variants. Make sure you've installed ActiveStorage in your Rails app before using `Spina::Parts::Image`.

You can render images in two ways: 
- using an image_tag
- using a URL

## Theme configuration

```
config.parts = [
  # ...
  {
    name: "header_image",
    title: "Header image",
    part_type: "Spina::Parts::Image"
  }
]
```

## Image tag example

```
<%= content.image_tag(:header_image, {resize_to_fill: [200, 200]}, {class: 'image'}) %>
```

This `content` helper will automatically add an `alt` attribute to the image. You can change the alt text when editing pages in Spina.

## Image URL example

```
<div style="background-image: url(<%= content.image_url(:header_image, {resize_to_fill: [1280, 200]}) %>)"></div>
```
