The InlineImage field represents an image input. This field supports drag and drop upload, or via clicking on the image to select media from the local filesystem.
Below is a simple example of how InlineImage could be implemented in in an Inline Form.
import ReactMarkdown from 'react-markdown'
import { useForm, usePlugin } from 'tinacms'
import { InlineForm, InlineImage } from 'react-tinacms-inline'
// Example 'Page' Component
export function Page(props) {
const [data, form] = useForm(props.data)
usePlugin(form)
return (
<InlineForm form={form}>
<InlineImage
name="hero_image"
parse={media => media.id}
uploadDir={() => '/public/images/'}
alt="hero-image"
/>
</InlineForm>
)
}There are two ways to use InlineImage, with and without children. If no children are passed, InlineImage will render a default img element. However, you may want more control over the image behavior, in which case you can pass children to InlineImage.
| Key | Description |
|---|---|
name | The path to some value in the data being edited. |
parse | Defines how the actual front matter or data value gets populated. The name of the file gets passed as an argument, and one can set the path this image as defined by the uploadDir property. |
uploadDir | Optional Defines the upload directory for the image. All of the post data is passed in, fileRelativePath is most useful in defining the upload directory, but you can also statically define the upload directory. |
previewSrc | Optional Defines the path for the src attribute on the image preview. If using gatsby-image, the path to the childImageSharp.fluid.src needs to be provided. This defaults to the MediaStore's previewSrc method. |
focusRing | Optional Either an object to style the focus ring or a boolean to show/hide the focus ring. Defaults to true which displays the focus ring with default styles. For style options, offset (in pixels) sets the distance from the ring to the edge of the component, and borderRadius (in pixels) controls the rounded corners of the focus ring. |
className | Optional A string associated with a CSS class to extend the inline image container styled component. |
alt | Optional A string to pass for the alt attribute of the img element when not using the Render Props pattern. |
children | Optional Children need to be passed through the Render Props pattern to access src. |

type ImageRenderChildren = (props: ImageRenderChildrenProps) => React.ReactNodeThe parse function handles how the path gets written in the source data when a new image is uploaded. parse is passed the media object for the newly uploaded image. A simple return value could look something like this:
parse: media => media.idThe path depends on where images live in your project structure. uploadDir sets where those new images should live:
uploadDir: () => `/example-dir`The previewSrc provides a path for the image when inline editing is active (a.k.a when the CMS is enabled). When inline editing is not active (cms.enabled === false), the image will reference the path in the source data.
previewSrc is passed the current field value, the field path, and current form values. The return value should be the entire path to the image from the source data — e.g. /example-dir/image.jpg.
You can extend styles of the
InlineImagecontainer via styled-components or with aclassName.
Below is an example of an Inline Image field used in an Inline Block in a Next.js project.
import { useCMS } from 'tinacms'
import { BlocksControls, InlineImage } from 'react-tinacms-inline'
export function Image({ data, index }) {
const cms = useCMS()
return (
<div className="block">
<BlocksControls
index={index}
focusRing={{ offset: { x: 0, y: 0 }, borderRadius: 0 }}
insetControls
>
<InlineImage
name="src"
previewSrc={fieldValue => cms.media.previewSrc(`public${fieldValue}`)}
parse={media => `/img/${media.filename}`}
uploadDir={() => '/public/img/'}
className="img--wrap"
alt={data.alt}
focusRing={false}
/>
</BlocksControls>
</div>
)
}The className will apply corresponding styles to the Inline Image container div. In this case, the focusRing is false because the
Below is the same example, refactored to use the Render Props pattern:
import { useCMS } from 'tinacms'
import { BlocksControls, InlineImage } from 'react-tinacms-inline'
export function Image({ data, index }) {
const cms = useCMS()
return (
<div className="block">
<BlocksControls
index={index}
focusRing={{ offset: { x: 0, y: 0 }, borderRadius: 0 }}
insetControls
>
<InlineImage
name="src"
previewSrc={fieldValue => cms.media.previewSrc(`public${fieldValue}`)}
parse={media => `/img/${media.filename}`}
uploadDir={() => '/public/img/'}
className="img--wrap"
focusRing={false}
>
{props => <img src={props.src} alt={data.alt} />}
</InlineImage>
</BlocksControls>
</div>
)
}With this pattern, the src is passed as a prop to the render children. The value of src will either be the return value from the previewSrc function (when the CMS is enabled) or the value stored in the source data (when the CMS is disabled).
Below is an example of how you could pass children as a to InlineImage to work with Gatsby Image. Notice how children need to be passed via render props.
You'll notice that this component looks a bit different with its handling of src. Since with Gatsby Image, the path to the image is transformed, you'll need to provide a fallback src that references the transformed path from childImageSharp.
Also, the previewSrc function uses the third argument, formValues to access the entire form and retrieve the transformed, childImageSharp path.
