About This Workflow
Overview
This n8n workflow automates the image generation process using OpenAI's API, incorporating specific brand guidelines to ensure consistency and quality. It starts by receiving image context and a title via a workflow trigger. The set_brand_guidelines node injects a detailed set of visual instructions, mimicking a newsletter's aesthetic, into the prompt. The generate_image node then sends this enhanced prompt to OpenAI's image generation endpoint. The output is converted to a binary format suitable for Slack, and then two Slack messages are sent: one announcing the generated image with its title, and another sharing the image itself. This workflow solves the problem of creating visually cohesive and on-brand imagery programmatically, saving time and ensuring brand alignment across different communication channels.
