How to Upload a Readme Image

Updated on 05 August, 2026

Upload a readme image to a Vultr Marketplace app using the Vultr Console or Vultr API to embed screenshots and diagrams in your app's public readme content.

Uploading a Readme image stores an image on Vultr's servers and returns a URL you can reference in your Readme or application instructions Markdown.

This guide explains how to upload a Readme image using the Vultr Console or the Vultr API.

  • Vultr Console
  • Vultr API

Upload images by copying and pasting, dragging and dropping, or clicking the Upload Image icon in the Readme or App Instructions editor toolbar. Uploading through the editor stores the image in Vultr Object Storage automatically.

Send a POST request to the Create a Marketplace App README image endpoint. Replace BASE64-IMAGE with a base64-encoded image.

console 
$ curl "https://api.vultr.com/v2/marketplace/apps/readme/images" \
    -X POST \
    -H "Authorization: Bearer ${VULTR_API_KEY}" \
    -H "Content-Type: application/json" \
    -d '{
        "image_b64": "BASE64-IMAGE"
    }'

The response contains the image's image_url. Reference this URL in your Readme or application instructions Markdown.
