What Google Flow is
Flow started as a video tool and, in February 2026, Google expanded it into a fuller creative studio that brings image and video into one workspace. Google folded features from its earlier experiments Whisk and ImageFX into it. For blog work, the important part is image generation.
Which image model does Flow use?
On 26 February 2026 Google launched Nano Banana 2, technically Gemini 3.1 Flash Image, and made it the default image model in Flow. Reports at launch said it is available to Flow users at zero credits and can create several images per prompt. It keeps the character and object consistency of the Pro version at faster speed, and it can render readable text. Nano Banana Pro remains available to some paid Google plans.
Plans and limits change often. Before you plan a big batch, open Flow and check what your own Google account includes.
Using Flow by hand
- Open Flow and sign in with your Google account.
- Start a new project and choose image creation.
- Write a prompt and pick an aspect ratio.
- Generate, pick the best image and download it.
- Rename and upload it to WordPress yourself.
Fine for one image. For ten images per post, it becomes the slow loop.
Using Flow through Pin Magic
Pin Magic's Flow tab drives the Flow page in your browser using your own Google session.
- Prompts come from your post. The side panel lists each section's prompt.
- Aspect ratio is set for you. The featured image uses 16:9 landscape. Section images use 9:16 vertical. A square 1:1 option is also supported.
- Download size is your choice. 1K is the original size. 2K and 4K are upscaled.
- Parallel tabs. Run 1, 3, 5, 8 or 10 at once. Start with fewer.
- Delay. A random pause between actions keeps the run steady and gives the page time to respond.
- Controls. Start batch auto-run, Resume batch and Stop batch.
- Retries. If a prompt does not register or a generation fails, the run tries again, and it pauses if you go offline instead of burning through attempts.
When the run finishes, press Insert all and the images go into WordPress. See how to add images to blog posts automatically.
Settings that suit blog images
| Setting | Suggested starting point |
|---|---|
| Featured image ratio | 16:9 (set automatically) |
| Section image ratio | 9:16 (set automatically) |
| Download size | 1K for in-article images; 2K for featured if your theme shows it large |
| Parallel tabs | 3 |
| Delay | The default range, then adjust if the run stalls |
Tips for steady runs
- Stay signed in to Flow with the account you use for generation.
- Close tabs you do not need. Browsers slow down background tabs, and fewer tabs make runs more stable.
- Lock the prompt list before starting so it cannot change halfway through.
- If Flow shows an error or a limit message, wait and Resume rather than restart.
- Keep the extension updated. Flow's page layout can change, and the extension may need an update to match.
Watermarks and labeling
Google marks images made with Nano Banana models with an invisible SynthID signal. For your site, this means AI images can be recognized as AI-generated by tools that check it. Disclosing how images were made is a good trust habit, especially when an image could be mistaken for a real photo. If you sell through Google Merchant Center, product images made with AI must carry specific metadata; see ecommerce blog image automation.
What to do after generating
Generating is not the end. Review each image, fix alt text and check the order in the post. Google's guidance on AI-assisted content says to review generated content, including alt text, before publishing. Then run internal linking on the post and consider pins for Pinterest.
Frequently asked questions
Is Google Flow free?
Image generation in Flow was reported to cost zero credits at the time of writing, but limits depend on your plan and can change. Check your account.
Do I need to install anything other than the extension?
No. You need a Google account and the Pin Magic extension in Chrome, Edge or Brave.
Can I choose the model?
You use whichever image model Flow offers to your account. Pin Magic automates the Flow page; it does not change the model.
Why did my batch stop?
Common causes are a Flow limit, a sign-in problem or too many parallel tabs. Lower the tabs, check Flow, then Resume.
Conclusion
Flow gives you a capable image model, and Pin Magic turns it into a section-by-section production line for your blog. Write strong prompts, keep the settings simple and review what comes out. Start with how to write image prompts for blog posts.
