Bulk AI Image Generator

Turn a list of ideas into a library of ready-to-use images. Automatically, for about a penny each.

n8n workflow canvas for the bulk AI image generator: read topics from a sheet, generate five prompt variations, create each image with Gemini and upload to Google Drive

Every business needs fresh visuals: blog headers, social posts, service pages, ads, Google Business Profile updates. Getting them usually means hours of stock-photo browsing, back-and-forth with a designer, or typing prompts into an AI tool one image at a time.

We built a system that does it for you. Type your topics into a spreadsheet, press one button, and come back to a folder of finished images.

How it works (the short version)

  1. You list your topics in a simple Google Sheet, one idea per row. "Cozy coffee shop on a rainy morning." "Physiotherapist helping a runner stretch." "Modern laneway home at dusk."

  2. AI writes the creative brief. For each topic, the system writes five different image concepts: different styles, angles, moods and lighting. You get real variety, not five copies of the same picture.

  3. AI creates the images. Each concept becomes a finished image.

  4. Everything lands in your Google Drive. Neatly named and organized by topic, and your spreadsheet updates itself so you can see what's done.

That's it. No design software, no prompt-writing skills, no copying and pasting.

Why it matters

Hours back every week

What used to take an afternoon of searching, prompting and downloading now runs on its own while you do something else. Ten topics means fifty images, with no extra effort from you.

About 1¢ per image

Compare that to stock-photo subscriptions, per-image licensing, or design hours. Even a big batch of a few hundred images costs less than a coffee meeting.

Built to scale

One topic or one hundred, the process is the same: add rows, press go. It's ideal for agencies, multi-location businesses, or anyone publishing content on a regular schedule.

Variety built in

Five distinct takes on every topic, from photorealistic and illustrated to moody or bright and airy, so you can pick the image that fits the page instead of settling for whatever turned up.

Original images, not stock

The images are made fresh for you, so you won't see the same photo on a competitor's website. That's better for your brand, and better for standing out in search and social.

Runs on tools you already use

Google Sheets in, Google Drive out. No new platform to learn, and your team can add topics from anywhere.

Who it's for

  • Local businesses that need a steady flow of visuals for their website, Google Business Profile and social channels
  • Content and SEO teams producing blog posts and landing pages at volume
  • Agencies managing visuals for several clients at once
  • Anyone tired of paying for stock photos that look like stock photos

Want to run it yourself? We're sharing the automation template we built. It runs in n8n, a free, open-source automation tool, and connects to Google Sheets, Google Drive and Google's Gemini AI.

What's included:

  • Setup notes inside each step
  • The spreadsheet column layout: topic, status, images_generated, last_run

What you'll need: an n8n account (self-hosted or cloud), a Google account, and a Gemini API key with billing turned on (image generation isn't on Google's free tier).
