# View Image - Workflow node | Docs - nodulz

Source: https://nodulz.com/docs/nodes/view_image

Language: en

Display an image from a URL or base64 data

## Usage and specifics

Prepare an image preview from a URL or base64. MIME type and alternative text describe the image; this is not file hosting.

Technical type : `view_image`. Runtime : `nodulz`.

## Credentials and prerequisites

This node defines no dedicated external credential. Remote sources or execution targets may still need their own access credentials.

See the [credentials guide](/docs/credentials) if a remote source or execution target requires access.

## Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

| Parameter | Type | Default | Values / limits |
| --- | --- | --- | --- |
| `sourceType` | `enum` | `"url"` | `url`, `base64` |
| `source` | `string` | `""` | - |
| `mimeType` | `string` | `"image/webp"` | - |
| `alt` | `string` | `""` | - |

## Configuration help

| Setting | Purpose and guidance |
| --- | --- |
| `sourceType`<br>Source type | Direct URL, workflow field, or base64 data. |
| `source`<br>Image source | Direct URL or path to an HTTP response (e.g. nodes.http1.body). Binary images (webp, png…) are detected automatically. |
| `mimeType`<br>MIME type | Explicit MIME type when not auto-detected. |
| `alt`<br>Alt text | Alternative text shown if the image fails to load. |

## Examples

- HTTP: nodes.http1.body after a GET image/webp
- Base64: nodes.http1.body.data or {{ nodes.edit_image1.data }}

## Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

```json
{
  "sourceType": "url",
  "source": "",
  "mimeType": "image/webp",
  "alt": ""
}
```

## Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
