AI Visual Content Playbook: On-Brand Images with Your Own GPT or Gemini Key

A practical system for creating consistent marketing visuals with AI image generation

For many startups, visuals are the slowest part of content production. Copy can be written quickly; finding or designing a suitable image takes longer. AI image generation changes this, but speed without direction produces images that look like everyone else's. This playbook gives you a system.

1. Define Visual Brand Rules

DecisionExampleWhy it matters
ColoursDeep red, cream, charcoalRecognition across every channel
StyleEditorial photographyConsistency between campaigns
MoodWarm, confident, practicalEmotional fit with your brand voice
SubjectsSmall teams at work, real objectsRelevance to your buyer

Your brand archetype result in MPO Engine already gives you a colour palette and voice. Use it as the starting point for these rules.

2. The Five-Part Prompt

Describe Five Things

1
Subject

What is in the image.

2
Setting

Where it takes place.

3
Style

Photographic, illustrated, flat, 3D or editorial.

4
Light and colour

The mood and the palette.

5
Composition

Framing, angle and space for a headline.

Weak: "Team meeting."
Strong: "Three colleagues reviewing a printed sales chart at a wooden table in a bright office with plants, editorial photography, warm daylight, deep red and cream tones, wide frame with empty space on the left for a headline."

3. Formats by Channel

ChannelFormatGuidance
LinkedIn / Instagram feedSquare or portraitOne clear subject, strong contrast
Blog headerWideLeave room for the title
EmailWide or square, lightMust work at small sizes
AdsPlatform-specificSingle focal point, minimal detail

4. Avoiding the Generic AI Look

5. Bring Your Own Key

Connecting your own OpenAI or Google key means images are generated on your own account. You choose the provider and model family, you control spending and limits directly, and your capacity grows with your needs.

Key Insight: In the MPO Engine Content Generator, if your own key reaches its usage limit, you receive one free fallback generation from our LLM APIs so a limit never stops a campaign halfway. Top up or raise your key limit to continue.

6. A Review Workflow

Before Anything Is Published

1
Generate options

Create two or three variations for each piece.

2
Check the rules

Compare against colours, style, mood and subjects.

3
Check accuracy

Look for distorted hands, objects, logos or misleading scenes.

4
Pair with copy

Confirm the image supports the message, not just the topic.

5
Save the prompt

Keep successful prompts as reusable templates.

7. Responsible Use

8. Measuring Impact

Compare engagement on posts and emails with generated visuals against your previous baseline: click-through, engagement rate and time to produce each piece. The goal is not only better-looking content but faster, more consistent production.
