Paste into ChatGPT or ClaudeUpload this exact original to my media library, titled “Summer garden”, with the alt text “Flowers beside a garden path”. Don’t redraw it or create a post. Check the saved image.

Creates a draft. Standard and Trusted do this on their own; Read only can’t.

  1. In ChatGPT, attach the image. Your assistant uploads the original file with upload_image_file and checks it arrived unchanged.
  2. In Claude, your assistant gives you your site’s WordPress upload page with request_upload. Choose the file there and say when it’s done.
  3. Your assistant finds the saved image and checks its title and alt text.
  • “…and set it as the featured image of my spring post.”
  • JPEG, PNG, GIF or WebP, up to 5 MB. For SVG, see Add an SVG logo or icon.
  • Retrying the same upload doesn’t create a second copy.
  • Claude can’t pass attachments on to other apps yet, which is why it uses the upload page.
