Generating one image in Gemini is easy. Generating 30 or 40 images for the same project is where the repetitive work starts.
If you're creating a YouTube story, comic, storyboard, or any other project that needs a sequence of images, the process can quickly become:
Paste a prompt. Wait for the image. Download it. Rename the file. Paste the next prompt. Wait again. Download again.
By image 20, most of your time isn't being spent creating prompts anymore. It's being spent managing the generation and download
Gemini Auto Image Saver is a Chrome and Edge extension designed to automate that repetitive part of working with images on Gemini.
It works directly with gemini.google.com and can automatically save newly generated images or process a list of prompts one at a time.
The extension doesn't create or rewrite your prompts. You provide the prompts, and Gemini generates the images. Gemini Auto Image Saver simply handles the repetitive workflow around them.
What Gemini Auto Image Saver Does
There are two main ways to use the extension.
Auto Save is useful when you prefer entering prompts into Gemini yourself. Whenever Gemini finishes generating a new image, the extension automatically downloads it using an organized filename.
Batch Prompts is designed for projects where you already have many prompts prepared. You paste the prompts into the extension, and it processes them sequentially in your open Gemini tab.
For each prompt, the extension submits the text to Gemini, waits for a new image to finish generating, downloads it, and then moves to the next prompt.
You don't need to keep reopening the extension popup while the batch is running. You can close the popup and keep the Gemini tab open.
chrome://settings/downloads
In Edge, open:
edge://settings/downloads
Turn off "Ask where to save each file before down."
If this setting remains enabled, your browser may ask you where to save every generated image, which defeats the purpose of automating the downloads.
You can also pin Gemini Auto Image Saver to your browser toolbar for easier access.
Option 1: Automatically Save Images You Generate Manually
If you like writing and submitting your prompts manually in Gemini, you can use Auto Save.
Open gemini.google.com, then click the Gemini Auto Image Saver extension.
Under the Auto Save section, choose your project name and filename prefix.
For example:
Project name: My YouTube Story
Filename prefix: scene_
Next image: 1
Make sure Auto Save Images is enabled.
Now continue using Gemini normally.
When a new image finishes generating, the extension detects it and saves it using your chosen naming structure.
The extension intentionally ignores images that were already present when the page was opened. Auto Save is designed to detect newly generated images.
There's also a Download Last Image option if you need another copy of the most recent image. The copy is identified separately rather than incorrectly advancing your normal sequence.
Option 2: Batch-Generate Images From a List of Prompts
Batch Prompts is useful when you've already prepared all the image prompts for a project.
For example, perhaps you've written a YouTube story and created one image prompt for every scene.
Instead of manually copying each prompt into Gemini, you can give the sequence to Gemini Auto Image Saver.
First, open Gemini and keep that tab open.
Set your project name, filename prefix, and starting number in the Auto Save section.
Then open Batch Prompts and paste your prompts using separators such as:
===PROMPT===
Cinematic 16:9. Same character. Dorm room at night...
===PROMPT===
Same character walking to class, morning light...
===PROMPT===
Same character sitting inside a lecture hall...
The extension also recognizes separators including:
---PROMPT---
===SCENE===
SCENE 1:
SCENE 2:
Click Parse Prompts so the extension can identify the individual prompts.
Then click Start Batch.
**Sample prompt format **
===PROMPT===
Cinematic 16:9 illustration of a young Black man sitting alone at a desk late at night, working on his laptop, warm desk lamp lighting, dark bedroom background, professional digital illustration.
===PROMPT===
Cinematic 16:9 illustration of a futuristic city at night, tall glass skyscrapers covered in glowing signs, wet streets reflecting the lights, a few cars driving through the city, dramatic atmosphere, professional digital illustration.
===PROMPT===
Cinematic 16:9 illustration of a lone astronaut standing on the surface of Mars, looking toward a small futuristic base in the distance, enormous mountains on the horizon, dramatic sunset, highly detailed professional digital illustration.
If the Send control appears disabled, click once inside Gemini's chat box.
From there, Gemini Auto Image Saver works through the queue one prompt at a time.
It submits a prompt, waits for Gemini to generate a new image, saves that image, and then continues to the next prompt.
The batch statistics let you see how many prompts have been completed and how many remain.
You can close the extension popup while this happens, but keep the Gemini tab open. For long batches, don't allow the computer to sleep while the process is running.
Tips for More Reliable Batches
For the simplest workflow, keep one Gemini tab open while running a batch.
If you've just updated or reloaded Gemini Auto Image Saver through chrome://extensions, refresh your Gemini page before starting.
If a scene fails, use the available Retry or Resume controls rather than restarting everything. Completed scenes are tracked so they aren't unnecessarily sent again.
It's also important to understand what the extension doesn't do.
Gemini Auto Image Saver doesn't rewrite prompts or automatically create consistency between your images. If you're creating a story and need the same character, clothing, environment, camera style, or visual style across multiple scenes, include those instructions in your prompts yourself.
The extension's job is to process the text you've already prepared and organize the resulting downloads.
