Node catalog Transformations

On this page

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 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

sourceType Source type: Direct URL, workflow field, or base64 data.
source Image source: Direct URL or path to an HTTP response (e.g. nodes.http1.body). Binary images (webp, png…) are detected automatically.
mimeType MIME type: Explicit MIME type when not auto-detected.
alt 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.
