Generate a placeholder image with custom colors, text and font.

## Setup and use

Run manually. Change the image properties in **Generate the image** in Open Flow or **Set Image Properties** in n8n. The example requests a 600 × 400 PNG with the text “Generated!”.

## Behavior

DummyJSON generates the image using the requested size, background and text colors, text, font size, font family and format. Open Flow returns a file object containing a name, MIME type and base64 content; n8n returns the downloaded image as binary data. Open Flow’s Code fetch accepts responses up to 1 MiB. The endpoint must be reachable and may impose its own limits.

## Changes to the source

*   Open Flow returns the image bytes in a base64 file object.
