Instagram Content Image Generator#

Create feed posts, stories, reels covers, and carousel graphics optimized for Instagram's algorithm and visual standards.

Workflow#

Step 1: Understand the Content Goal#

Ask (if not provided):

• What format? (feed post / story / reels cover / carousel)
• What niche? (e.g., food, fitness, fashion, tech, travel)
• What's the goal? (engagement, traffic, brand awareness, sales)
• Personal brand or business?

Step 2: Apply Algorithm-Aware Decisions#

Read references/algorithm.md for:

• Format selection based on reach goals
• Caption and hook strategies that boost ranking
• Hashtag and engagement optimization
• Avoid patterns that reduce distribution

Step 3: Apply Visual Style#

Read references/design-style.md for:

• Aesthetic selection by niche
• Color palette and typography rules
• Layout patterns per format
• Visual consistency for brand building

Step 4: Generate with Rendshot#

Feed Post (1080x1080):

text

generate_image({
  prompt: "Instagram feed post for a coffee brand, minimal aesthetic, large serif title 'The Art of Pour Over', warm brown palette, clean white background, product photo area at center",
  platform: "instagram_post",
  locale: "en"
})

Story (1080x1920):

text

generate_image({
  prompt: "Instagram story for a fitness coach, bold modern design, title 'CHEST DAY ROUTINE', neon accent on dark background, numbered list layout for 5 exercises",
  platform: "instagram_story",
  locale: "en"
})

Carousel (multi-call): Generate each slide individually with consistent style:

text

// Slide 1 — Cover
generate_image({
  prompt: "Instagram carousel cover slide, '5 Python Tips You Need', modern tech aesthetic, dark theme with green accents, bold sans-serif",
  platform: "instagram_post"
})

// Slide 2-5 — Content slides (use create_template for consistency)
generate_image({
  template_id: "tpl_carousel_slide",
  variables: { slide_number: "1", tip_title: "F-Strings", code_snippet: "..." }
})

Using templates:

text

list_templates({ platform: "instagram_post", q: "product showcase" })
get_template({ template_id: "tpl_xxx" })
generate_image({ template_id: "tpl_xxx", variables: { ... } })

Step 5: Save for Brand Consistency#

text

create_template({
  name: "Coffee Brand IG Post",
  html: "<returned html>",
  variables: [...],
  platform: "instagram_post",
  tags: ["coffee", "minimal", "brand"]
})

Carousel Best Practices#

• Slide 1: Hook — bold title, curiosity gap, no text wall
• Slides 2-N: One idea per slide, consistent layout template
• Last slide: CTA ("Save this", "Follow for more", "Link in bio")
• Use create_template after first slide to lock the layout for remaining slides
• Optimal length: 5-10 slides (algorithm favors time-on-post)
