What is Image Description?

Image Description is a textual description of the image content, usually used for:

  • SEO Optimization
  • Accessibility (Alt Text)
  • Content archiving and management

Example:

A brown cat sitting on a windowsill looking outside, sunlight streaming in, cozy indoor scene

The focus is on clarity, accuracy, and high readability, not necessarily considering generation effects.

What is Image Prompt?

Image Prompt is the input prepared for AI image generation models, used to generate new images. It not only describes the image content but also emphasizes style, composition, and details.

Example:

"A realistic brown cat sitting on a windowsill, sunlight streaming in, cozy indoor scene, cinematic lighting, 4K resolution"

Prompt focuses more on generation effects, rather than just describing the image.
