How to Generate AI Images: Complete Beginner's Guide
Generating images with AI has never been easier. Whether you want photorealistic portraits, digital art, or product mockups, modern AI tools can create them from a simple text description. This guide walks you through everything you need to know.
What Is AI Image Generation?
AI image generation uses deep learning models to create images from text prompts. You describe what you want — "a golden retriever wearing sunglasses on a beach" — and the AI produces a matching image in seconds.
The technology behind this is called diffusion models (like Stable Diffusion and DALL-E) or multimodal transformers (like Google Gemini). These models have been trained on billions of images and understand the relationship between text descriptions and visual concepts.
Step 1: Choose Your Tool
The first decision is which AI image generator to use. Here's what matters:
ImgCraft (Recommended)
ImgCraft uses Google Gemini 2.5 Flash, one of the most capable multimodal AI models available. It generates images in under 5 seconds with excellent prompt understanding.
- Free tier: 2 credits per day
- Speed: ~5 seconds per image
- Quality: Photorealistic to artistic styles
- Editing: Built-in AI editor for refinements
Other Options
- Midjourney: Great for artistic images, but requires Discord
- DALL-E 3: Good quality, available through ChatGPT
- Stable Diffusion: Open-source, requires technical setup
Step 2: Write Effective Prompts
The prompt is everything. A well-written prompt produces dramatically better results than a vague one.
Prompt Structure
Use this formula: Subject + Style + Details + Mood + Technical specs
Bad prompt: "a cat" Good prompt: "A fluffy orange tabby cat sitting on a windowsill, golden hour lighting, warm tones, shallow depth of field, photorealistic"
Key Elements to Include
- . Subject: What's in the image (person, object, scene)
- . Style: Photorealistic, oil painting, watercolor, anime, etc.
- . Lighting: Golden hour, studio lighting, dramatic shadows
- . Composition: Close-up, wide angle, bird's eye view
- . Mood: Cheerful, mysterious, serene, dramatic
- . Details: Colors, textures, materials, backgrounds
Advanced Prompt Techniques
- Negative prompts: Specify what you DON'T want — "no text, no watermark, no blurry"
- Style references: Mention artistic styles — "in the style of Studio Ghibli"
- Technical terms: Use photography terms — "85mm lens, f/1.4, bokeh"
- Aspect ratios: Specify dimensions — "16:9 landscape" or "9:16 portrait"
Step 3: Generate and Iterate
Don't expect perfection on the first try. The best results come from iteration:
- . Start broad: Generate with your initial prompt
- . Evaluate: What's good? What needs changing?
- . Refine: Adjust the prompt based on results
- . Variations: Try different styles or angles of the same concept
- . Edit: Use AI editing to fix specific areas
With ImgCraft's editor, you can generate an image and then use AI to edit specific parts — change the background, adjust colors, add elements, or remove objects.
Step 4: Choose the Right Style
AI can generate images in virtually any visual style:
Photorealistic
Best for: Product photos, headshots, real estate, social media Tips: Use photography terms, mention camera models, specify lighting
Digital Art
Best for: Social media graphics, illustrations, concept art Tips: Reference specific art styles, mention color palettes
Anime / Manga
Best for: Character design, fan art, illustrations Tips: Mention specific anime styles, use terms like "cel-shaded"
Oil Painting / Watercolor
Best for: Wall art, decorative prints, artistic projects Tips: Mention "brush strokes," "canvas texture," "impasto"
Common Mistakes to Avoid
- . Too vague: "A pretty picture" won't produce good results
- . Too complex: Don't cram 10 subjects into one prompt
- . Conflicting instructions: "Dark and bright" confuses the AI
- . Expecting text: AI struggles with text in images — keep it minimal
- . One and done: Not iterating on your prompts
Use Cases for AI Images
AI-generated images are used across industries:
- **E-commerce**: Product photos without a photographer
- **Social media**: Custom graphics and thumbnails
- Marketing: Ad creatives, banners, email headers
- Personal: Avatars, wallpapers, gifts
- **Professional**: Headshots and portraits
