Queue Manager for Google Flow — Nano Banana Batch Automation

Batch Nano Banana image prompts in Google Flow with queues, CSV import, retries, upscaling, and organized downloads.

🎨 Take control of your image generation workflow on Google Flow! Queue Manager for Google Flow is a free Chrome extension for batch image generation with Nano Banana. Import multiple prompts, run them in order, and automatically save the results to organized project folders. Build image batches for storyboards, social posts, illustrations, product concepts, and other creative projects. Spend less time copying prompts, watching for results, and renaming files. ✨ FREE EXTENSION. EVERY FEATURE INCLUDED. • No extension subscription or paid tier. • No extra account, sign-up, or approval queue. • No extension-imposed prompt cap or extension credits. • Queue copies and settings stay in your browser, with no automatic upload to the developer. Google Flow access, model availability, credits, and service limits still apply. Prompts you run are sent to Google Flow for processing. 🚀 WHAT YOU CAN DO 1. Import multiple prompts from text or CSV Paste a prompt list or upload a .txt or .csv file. Use one prompt per line, blank lines between multiline prompts, or your own separator. For CSV imports, choose the prompt column and an optional filename column. Check the prompt count and preview before adding the batch. 2. Edit and reorder your queue Open Edit Queue while the queue is stopped to refine pending prompts, move scenes up or down, and add or remove entries. Preview the before-and-after queue IDs before saving. Custom filenames imported from CSV are preserved. 3. Track progress and stay in control See completed, running, pending, skipped, and failed jobs in the side panel, along with average job time and estimated time remaining. Skip pending prompts, stop a run, or switch to another tab while watching progress. Keep the Google Flow project tab open and Chrome running. 4. Retry failed jobs without repeating completed work Failed jobs show an error message. Once the queue is finished or stopped, use Retry for one failed prompt or Retry All Failed for the failed items. Some connection, project, or submission problems pause the queue so you can check Flow before continuing. 5. Auto-download with useful filenames Save generated images into a project folder inside Downloads. Use sequential names such as 001.jpeg and 002.png, add a prefix such as scene_, or supply filenames through CSV. The extension preserves the original image format and bytes; it does not convert every image to PNG. A new download with the same target filename replaces that file. 6. Request optional 2K image upscaling Enable Auto-download and Upscale to 2K to request supported high-resolution image outputs. The queue waits for the requested download to finish before moving on. If the upscale option or its download cannot be confirmed, the job reports an error. 7. Set the pace between prompts Choose a minimum and maximum delay between jobs. The default range is 5–10 seconds, with a minimum of 5 seconds and an upper value at least 5 seconds higher. Adjust the timing to your workflow; Google Flow's own limits still apply. 8. Export your queue and results Save a Queue CSV with prompts and filenames that you can import again later. Export a Results CSV with job statuses, filenames, errors, and timing information to review the batch. 9. Check readiness and choose your theme The extension checks the Flow page before starting and reports missing or changed controls. Use the light or dark side-panel theme and view the installed version directly in the header. 🛠️ GET STARTED 1. Open a Google Flow project in Chrome and choose your image-generation settings. 2. Click the Queue Manager icon to open the side panel. 3. Select Import, paste your prompts or upload a TXT / CSV file, and review the preview. 4. Set your download folder, optional filename prefix, and delay range. 5. Enable Auto-download and optional Upscale to 2K if needed. 6. Click Start. Keep the Flow project tab open while the batch runs. 💬 COMMON QUESTIONS Is Queue Manager for Google Flow free? Yes. All extension features are free, with no extra account or extension prompt quota. Google Flow is a separate service and may require account access, credits, or payment. The extension does not bypass Google's limits. Can I import prompts written in ChatGPT? Yes. Copy the prompts into a text list or save them as TXT or CSV, then use Import. Choose a separator that keeps each prompt together and check the preview. There is no direct connection to your ChatGPT account. Can I work in another tab while images generate? Yes. Keep the Flow project tab open and leave its generation controls alone. You can view progress and press Stop from another tab. Controls that would change the running queue are restricted while you are away, with a Switch to Active Tab button to return. What happens when I press Stop? The queue stops starting new jobs and lets the current job finish where possible. Pending prompts remain in the queue for later. Skip applies to pending prompts; it does not cancel an image already being generated. Does this extension generate videos? Version 1.4.0 supports image-generation batches. Video generation is not supported. Why does Chrome briefly show a debugging banner? The extension uses Chrome's debugger permission briefly to activate Flow's Generate button, then disconnects. It does not use that permission to record your browsing or inspect network traffic. No Developer Mode or separate app is needed for the Chrome Web Store version. 🛡️ PRIVACY AND DATA USE The extension uses your imported prompts, relevant Flow page content, project information, and limited activity information to run the queue, detect results, and save files. It checks tab URLs to identify the selected Flow project and observes limited Flow request metadata for troubleshooting. Queue copies, settings, and preferences are stored locally in Chrome. There is no developer-operated analytics service, advertising, or automatic diagnostic upload. Running a queue submits your prompts to Google Flow, and downloads retrieve generated images from their sources. Copy Support Diagnostics only copies a report to your clipboard. Review it before choosing to send it for support. The privacy policy explains local diagnostics, optional developer capture, retention, and deletion. WHAT'S NEW IN v1.4.0 • More reliable prompt submission and clearer recovery from interruptions. • Stopped-state queue editing with before-and-after IDs. • CSV import, filename prefixes, and reusable queue exports. • Original image formats preserved in organized downloads. • Refined monochrome interface, updated Q icon, and visible version label.
