Question 1

What is an image prompt?

Accepted Answer

An image prompt is the text description you give an AI image generator to tell it what to create — the subject, style, lighting, and other details that shape the final picture.

Question 2

How long should an AI image prompt be?

Accepted Answer

Most effective prompts run roughly 20-60 words: enough to specify subject, style, lighting, and mood, without so much detail that it confuses the model.

Question 3

What's the easiest way to learn prompt structure?

Accepted Answer

Run an image you admire through an image to prompt tool. Studying the structured output — subject, style, lighting, camera, colors, mood — teaches you the pattern to reuse in your own prompts.

Question 4

Do prompts need to be different for Midjourney vs Stable Diffusion?

Accepted Answer

Slightly. Midjourney and Stable Diffusion tend to favor comma-separated descriptive tags, while Flux and DALL-E generally respond better to a natural-language sentence. Picking a target model in the image to prompt tool formats the output accordingly.
