What is an Image Input Node

The Image Input node allows you to analyze and process images using advanced AI vision models. It can describe image content, extract information, answer questions about images, and perform various computer vision tasks by processing images from URLs or uploaded files.

​
Configuration

Model: Select the AI vision model to use for image analysis

  • o3-mini: Fast and efficient model for basic image analysis tasks
  • gpt-4o: Advanced model for detailed image understanding and complex analysis
  • gpt-4o-mini: Balanced option offering good performance with faster processing

Image URL: Provide the direct URL to the image you want to analyze

  • Must be a publicly accessible image URL
  • Supports common image formats (JPG, PNG, GIF, WebP)
  • Alternative to uploading image files directly

Image model prompt: Describe what you want the AI to do with the image

  • Be specific about what information you need extracted
  • Examples: “Describe the content of this image in detail”, “Count the number of people in this photo”, “What text is visible in this image?”

​
Outputs

The Image Input node provides processed information based on your prompt and the selected model’s analysis of the image.

​
How to set up the Image Input Node

  1. Add an Image Input node to your workflow
  2. Select your preferred AI model:
    • Choose o3-mini for quick, basic analysis
    • Choose gpt-4o for detailed, complex image understanding
    • Choose gpt-4o-mini for balanced performance
  3. Provide the image source:
    • Enter a direct Image URL for web-hosted images
    • Or upload an image file directly (if supported by your platform)
  4. Write your Image model prompt:
    • Be clear and specific about what you want to know
    • Include details about the type of analysis needed
    • Specify the format you want for the response
  5. Connect the Image Input node to downstream nodes in your workflow
  6. Test the node to ensure it processes your image correctly

Common Use Cases

  • Content Moderation: Automatically detect inappropriate or unsafe content in images
  • Product Cataloging: Extract product details, descriptions, and features from product photos
  • Document Processing: Extract text and data from scanned documents, receipts, or forms
  • Quality Control: Analyze product images for defects or compliance issues
  • Social Media Management: Generate captions and descriptions for social media posts
  • Accessibility: Create alt text descriptions for web images
  • Inventory Management: Count items or identify products in warehouse photos
  • Medical Imaging: Analyze medical images for preliminary screening (with appropriate oversight)
  • Real Estate: Generate property descriptions from listing photos
  • Education: Create study materials by analyzing diagrams, charts, or textbook images

​
Prompt Examples

  • General Description: “Describe everything you see in this image in detail”
  • Text Extraction: “Extract all visible text from this image and format it as plain text”
  • Object Counting: “Count how many [specific objects] are visible in this image”
  • Color Analysis: “What are the dominant colors in this image?”
  • Scene Understanding: “What is the setting or location shown in this image?”
  • Safety Assessment: “Identify any potential safety hazards visible in this workplace image”
  • Product Information: “List all the product features and specifications visible on this packaging”

​
Best Practices

  • Image Quality: Use high-resolution, clear images for better analysis results
  • Specific Prompts: Be precise about what information you need from the image
  • Model Selection: Choose the appropriate model based on complexity requirements
  • URL Accessibility: Ensure image URLs are publicly accessible and don’t require authentication
  • File Formats: Use standard image formats (JPG, PNG) for best compatibility
  • Privacy Considerations: Be mindful of privacy when processing images containing personal information

​
Troubleshooting

  • Image Not Loading: Verify the image URL is correct and publicly accessible
  • Poor Analysis Results: Try using a more detailed or specific prompt
  • Model Errors: Switch to a different model if you encounter processing issues
  • Slow Processing: Consider using o3-mini for faster results on simple tasks
  • Format Issues: Ensure your image is in a supported format and not corrupted
