Automatic featured images for Shopify blogs

Last updated: November 1, 2026

There is no native Shopify connector yet. Use the REST API or MCP server to render an image per article, or the signed webhook to push image URLs into your own automation that updates the blog post.

How to use it today

Render the image from the article URL, download the PNG from the returned link and upload it as the article image in Shopify. For many articles, use the webhook or call the API in a script.

curl -X POST https://contentimage.io/api/v1/render \
  -H "Authorization: Bearer ci_..." \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com/my-article","sizes":["og","featured"]}'

ContentImage is free during the beta. No card needed.
