It starts by fetching real-time news from a News API and filtering relevant articles for social media publishing. AI then analyzes the news and generates a professional LinkedIn post along with an image prompt. An AI image is created based on the news context and converted into a LinkedIn-compatible format. The system fetches LinkedIn profile details, registers the image upload, and uploads it using a secure URL. Finally, a LinkedIn post is published combining the news-based content and image, and a Slack notification is sent to confirm successful publishing.\n\n\n## Setup steps\n**1.** Fetch latest news using News API\n**2.** Filter relevant articles for social media use\n**3.** Generate LinkedIn post content + image prompt using AI\n**4.** Create image using OpenAI Image node\n**5.** Convert image into binary format\n**6.** Register LinkedIn media upload using profile info\n**7.** Upload image via PUT API using upload URL\n**8.** Create LinkedIn post with text + image asset\n**9.** Send Slack notification after successful post"
