Select the tool that matches your objective:

Before generating an image, answer these questions:

Step 4: Include Important Prompt Details

Professional prompts include:

  • Subject
  • Environment
  • Style
  • Lighting
  • Camera angle
  • Colors

Step 7: Edit and Refine

Improve your image by adjusting:

  • Background

This is especially important for businesses, agencies, and advertisers.


Step 10: Optimize for SEO

For website images:

  • Use descriptive filenames.

  • Compress images for faster loading.
  • Use modern image formats.

Example file name:

ai-cybersecurity-threat-detection-dashboard.webp

Example alt text:
