Create an [ImgBB account](https://api.imgbb.com/) and get your API key\n2. Add your ImgBB API key to the HTTP Request node (key parameter)\n3. Optional: Configure OpenAI credentials for image generation\n4. Connect your image input source\n\n## How to Adjust it to Your Needs\n- Skip OpenAI nodes if using your own image files\n- Adjust image optimization parameters\n- Customize image hosting settings\n- Modify output format for your needs\n\n\nMade by Simon @ [automake.io](https://automake.io)"}, "typeVersion": 1}, {"id": "8f4bfed3-820c-495d-9d5f-0dbdae7beb1a", "name": "Sticky Note53", "type": "n8n-nodes-base.stickyNote", "position": [80, 6400], "parameters": {"color": 3, "width": 620.0617659833041, "height": 218.46830740679286, "content": "**REQUIRED**\n\n**ImgBB - image hosting i.e. gives you an img url**\n1.
