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.

Queue Manager for Google Flow is a free Chrome extension for batch image generation with Nano Banana. Import multiple prompts, prepare your queue, 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. ✏️ Prepare your pending prompts before running Open Edit Queue only when the queue is fully stopped. Pending shows your editable prompts; All also shows Completed, Failed, and Skipped history as read-only. Copy any prompt, including unsaved edits, with its line breaks preserved. Add a prompt, remove a pending row, or use arrows to exchange prompts between the existing pending positions. The Before/After preview shows their queue IDs. Those positions keep their IDs; removing a row leaves other IDs unchanged, and adding a row creates an ID after the highest existing one. Custom filenames stay with their prompts. Changes apply only after Save changes succeeds; Cancel or closing discards the draft. 3. 📊 Follow each job and your whole batch See Preparing, Generating, Checking image, Preparing 2K, Upscaling, Cleaning image, and Downloading as work advances. The Current Job counter runs continuously from preparation through saving, without resetting between stages. It resets for the next job and continues when you reopen the panel or let submitted work finish after Stop or a queue pause. Total Time accumulates queue work and between-job waits across Stop, Start, and retries; stopped and idle paused time is excluded. Average time and estimated time remaining help you review the batch. 4. 🔄 Return failed prompts to Pending, then Start when ready Failed jobs show an error message. When the queue is fully stopped, use Retry for one failed prompt or Retry All Failed for all failed items. These actions return prompts to Pending without starting generation. Edit or reorder them first, then press Start to run all Pending prompts in queue order, including any already pending. Completed and Skipped history stays unchanged. IDs, custom filenames, and accumulated Total Time are preserved. A retry is confirmed only after it is saved. 5. 📂 Auto-download with useful filenames Save generated images into a project folder inside Downloads. Use queue-based names such as 001.jpeg and 002.png, add a prefix such as scene_, or supply filenames through CSV. With watermark cleanup off, the extension preserves the original image bytes and filename extension rather than converting every image to PNG. A new download with the same complete target filename replaces that file. The queue waits for its requested downloads to finish. 6. 🔍 Request optional 2K image upscaling Enable Auto-download and Upscale to 2K to request supported high-resolution image outputs. If the upscale option or its download cannot be confirmed, the job reports an error. Keep the Flow project tab open and leave its download controls alone while it captures the selected output. 7. 🧹 Choose optional local visible-watermark cleanup Remove visible watermark is off by default under Downloads. Enable it with Auto-download to clean supported Flow sparkle marks locally, without uploading images to a cleanup service. Supported formats include verified JPEG, fully opaque PNG, and static WebP variants. Calibrated Original/2K sizes use exact placements. Bounded unfamiliar dimensions use a predicted position with stronger detection; real placement at those sizes, including 4K, remains unverified. If the mark or repaired result is uncertain, cleanup fails, or the image is unsupported, the original is saved. JPEG and WebP cleanup can change pixels outside the small repair area through compression; perfect restoration is not guaranteed. This feature does not remove SynthID or other invisible watermarks. 8. ⏱️ Set the pace between prompts The default random wait between finished jobs is now 1–5 seconds. Both bounds are adjustable: the minimum is 1 second, and the maximum must be at least 4 seconds higher. Raising the minimum raises the maximum when needed. Your existing valid saved range, including 5–10 seconds, is kept. These waits do not change generation or download timeouts or bypass Google's limits. 9. ⏸️ Stop, skip, and recover clearly Skip applies to Pending prompts; it cannot cancel a submitted image. Stop prevents further jobs from starting. It leaves unsubmitted work Pending and lets an already submitted generation or download settle. Some connection or project problems pause the queue so you can check Flow and continue with Start. An interrupted job whose outcome cannot be confirmed is marked Failed: inspect Flow and Downloads before retrying to avoid generating it twice. 10. ⚙️ Export, check readiness, and choose your theme Save a Queue CSV with prompts and filenames that you can import later. Export a Results CSV with statuses, filenames, errors, and durations. The extension checks the Flow page before starting and reports missing or changed controls. Choose the light or dark side-panel theme and see the installed version in the header. A one-time v1.5.0 popup summarizes the new features. 🚀 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 prompts or upload TXT / CSV, and check the preview. 4. While stopped, use Edit Queue to refine your Pending prompts and save changes. 5. Set your download folder, optional filename prefix, and delay range. 6. Enable Auto-download, optional Upscale to 2K, and optional Remove visible watermark as needed. 7. Click Start. Keep Chrome running and 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 them 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. Does Retry immediately run a prompt? No. Retry moves Failed prompts to Pending. You can edit them first. Start then runs every Pending prompt in queue order. 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 change an active queue are restricted, with a Switch to Active Tab button to return. Does watermark cleanup always change the image? No. Cleanup is optional and off by default. Unsupported or uncertain images keep their original bytes. When no supported mark is detected, the original is saved normally. Known sizes use calibrated placements; unfamiliar sizes within fixed limits need a stronger match at a predicted position. It does not remove invisible watermarks. Does this extension generate videos? Version 1.5.0 supports image-generation batches. Video generation and image-reference attachments in prompts are not supported. Why does Chrome briefly show a debugging banner? The extension briefly activates the selected Generate button with trusted browser input, then disconnects. Chrome may show its standard debugging banner during that action. No Developer Mode or separate app is needed for the Chrome Web Store version. 🔒 PRIVACY AND DATA USE The extension handles 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 backend, analytics service, advertising, or automatic diagnostic upload. Running a queue submits your prompts to Google Flow, and downloads retrieve generated images from their sources. Optional watermark cleanup happens locally; no image is sent to a cleanup service. Copy Support Diagnostics only writes 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 v1.5.0 • Pending/All queue editing, read-only history, Copy on every prompt, and fixed pending IDs with saved drafts. • Retry returns Failed prompts to Pending; Start runs them when you are ready. • Immediate stage status, a continuous whole-job counter, and cumulative Total Time. • A 1–5 second default wait, with adjustable bounds and existing valid settings preserved. • Optional local cleanup of supported visible Flow sparkle marks, with original-image fallback. • Clearer saved-change feedback, interrupted-job recovery, and one-time release notes. 💬 SUPPORT Report a bug or request a feature: https://docs.google.com/forms/d/e/1FAIpQLSdhVsP3lwX4UtaA9Vr29d87jOMcbr_D-jrnSsQ_VIRnl2l6vA/viewform 💬 Telegram support: https://t.me/queuemanagerforgoogleflow?direct 📢 Updates: https://t.me/queuemanagerforgoogleflow Queue Manager is an independent extension and is not affiliated with or endorsed by Google.
