Write Better Image Prompts and Negative Prompts

A prompt is the instruction you give CloudMySite before generating an image or logo. A good prompt is clear, specific, and written in normal language.

You do not need special prompt engineering skills. Think of the prompt as a short creative brief.

Prompt Basics​

For images, include:

  • what the image should show
  • where it will be used
  • the style or mood
  • important colors
  • what should be left out

For logos, include:

  • business name
  • audience
  • brand personality
  • symbol ideas
  • color direction
  • whether you want icon only or icon plus wordmark

Prompt Length​

CloudMySite shows a character counter for prompts. The image and logo prompt fields support up to 2100 characters.

Most strong prompts are much shorter than that. A good prompt is often 2 to 5 sentences.

Use the Enhance Prompt Button​

The Enhance prompt button can help turn a rough idea into a more complete prompt.

Use it when your prompt is too short, such as:

hero image for a florist

CloudMySite can help expand the idea with more style and composition details. After enhancement, review the prompt before generating.

Use Voice Input​

If your browser supports speech recognition, the microphone button lets you speak your prompt. This is helpful when you can describe the idea more easily than typing it.

After voice input, read the prompt and fix any misunderstood words before generating.

Negative Prompt Basics​

A negative prompt tells CloudMySite what to avoid.

Use it for unwanted visual traits, not for the main idea.

Examples:

blurry, low resolution, watermark, extra text, distorted hands
dark mood, cluttered background, cartoon style, messy typography
medical needles, scary imagery, harsh lighting, stock photo look

Negative prompts support up to 500 characters when your plan includes them.

When to Use a Negative Prompt​

Use a negative prompt when:

  • results are too blurry
  • unwanted text appears
  • the image feels too dark or cluttered
  • faces, hands, or objects look distorted
  • the style is too cartoonish or too realistic
  • the image includes items that do not fit your brand

Do not overload the negative prompt with too many unrelated items. A short list usually works better.

Prompt Examples by Use Case​

Homepage Hero​

Create a wide homepage hero image for a boutique interior design studio.
Show a bright living room with natural textures, soft neutral colors,
plants, warm sunlight, and an elegant editorial photography style.
Leave clean space on the left for headline text.

Negative prompt:

dark room, clutter, watermark, text, distorted furniture

Product Launch​

Create a square product visual for a new organic skincare serum.
Show a glass bottle on a stone surface with water droplets, botanical leaves,
soft beige and green colors, premium wellness brand style.

Negative prompt:

fake plastic look, harsh shadows, messy labels, unreadable text

Blog Header​

Create a wide blog header image about small business cybersecurity.
Use an abstract digital shield, soft blue light, laptop silhouette,
professional but approachable mood, no text.

Negative prompt:

hackers in hoodies, scary dark scene, red warning signs, text

Logo Brief​

Create a logo concept for GreenLoop Recycling, a community recycling pickup service.
The brand should feel clean, local, optimistic, and trustworthy.
Use a simple loop or leaf symbol, green and blue colors, minimal design.

Negative prompt:

trash piles, dirty textures, complex illustration, tiny unreadable text

Prompt Template​

Use this template when you are stuck:

Create a [image type] for [business or project].
Show [main subject]. Use [style], [colors], and [mood].
Make it suitable for [placement]. Avoid [things to avoid].

Example:

Create a banner image for a tutoring center.
Show a bright study desk with notebooks, laptop, and soft morning light.
Use a clean realistic style, blue and yellow accents, encouraging mood.
Make it suitable for a landing page section. Avoid text and clutter.

Common Prompt Mistakes​

Avoid prompts that are too vague:

make a nice image

Better:

Create a friendly hero image for a dog grooming business.
Show a clean grooming table, happy small dog, soft pastel colors,
bright welcoming salon, realistic photography style, no text.

Avoid asking for too many unrelated ideas in one image. If you need several visuals, generate them separately.
