When working on GPT Image 2.5 images in Flux Art on mobile, first confirm the selected file is the true original, then submit the task. After returning from the background, check the job first and verify the file after downloading instead of using screenshots. This article turns photo selection, task confirmation, file saving, and desktop acceptance into a handoff checklist, focusing on asset transfer and handover, not repeating full model onboarding.
From Album to Upload: Verify the Selected File First
In Photos or Files, locate the original source file first, confirm the subject is clear, orientation is correct, and no customer-private information is included. A preview saved in a chat app may not be the original file; a similar name does not prove the content is the same. In the system picker, only select files needed for this task, then after returning to the web page verify the thumbnail preview and file details. If a file is still in cloud storage or not fully downloaded, confirm it opens normally on your device before attempting upload.
Permission models for file selection differ across systems and browsers, so you should not assume each browser has a separate "allow all photos" switch. Follow the actual system prompts and authorize only the materials needed for the task. If selection fails, distinguish whether there are no files in the selector, unreadable files, unsupported formats, or upload errors after returning to the page; do not keep submitting empty tasks repeatedly.
| Handoff point | Records to keep | Stop condition |
|---|---|---|
| After selecting | Source image name, orientation, purpose, and authorization scope | File is not original or contains unrelated sensitive information |
| Before submission | Prompt, details to preserve, model, and current cost | Parameters not confirmed or reference image not loaded |
| Before leaving the page | Task ID or existing page status | Do not assume submission by screenshot alone |
| After returning to page | Current status for same account and same task | Do not resend before confirming a failed status |
| After downloading | Actual file name, pixels, and whether it opens completely | Only preview, screenshot, or partial download |
| Transferring to desktop | Original input, output, prompts, and acceptance criteria | Transferred with size loss from compression by transfer tools |
Check task status first when returning from the background, do not treat page reload as task failure
A mobile page can reload after switching apps or locking the screen. After returning, first confirm the logged-in account and task history, then judge whether generation is complete. If the input box is not preserved on the page, it does not prove the server did not accept the task. If there is no task ID or clear status, record time and error first, then confirm with official support to avoid duplicate tasks and extra charges caused by repeated clicks. This article did not test all system background behaviors and does not guarantee upload or download will always continue after screen lock.
Saving and handoff: verify real downloaded files, do not deliver screenshots
Safari downloads can be found in the iPhone Files app, and the exact folder depends on download settings. Do not assume results always land in Photos. Chrome on Android can find files from the download list. Confirm download completion first, then open the file to check actual dimensions. If not found, check browser download status and remaining device storage instead of regenerating immediately.
When handing off to a desktop, keep one copy each of the original input and result. Use a file transfer method that does not silently compress the original image, then re-check resolution and content on the receiving end. Name files by project, purpose, version, and date, and record the exact model and specification used. Before commercial use, still review text, logos, product structure, human details, and material rights; a shrunken mobile preview is not proof of final quality.

Detailed steps for mobile use
Enter https://flux-art.net/en/models/gpt-image-2-5 directly in the address bar, and do not use third-party top-up links or unfamiliar installation packages. After logging in to Flux Art, choose "Image Generation" to create a new image, or "Image Editing" to modify a photo from your library. Allow the browser to read only the files you intentionally select.
For quick composition, product shots, or posters, try Flare first. If you need to continue from a reference image to refine background, materials, and local details, try Sunburst first. When writing prompts, put required retention items near the front. Mobile typing is slower, so you can draft "subject-scene-composition-constraints" in Notes first, then paste after review to avoid deleting key details by mistake.
As of 2026-09-10, the page can select multiple quality tiers, Auto, 1K/2K/4K, and custom sizes. On cellular data, uploading originals and downloading high-resolution outputs both use mobile data. Start with one preview, then raise quality after direction is correct to better control time and cost. Dynamic pricing and entitlements are governed by what is shown on the mobile page before submission.
Two mobile-specific risks
The first is preview zoom. If it "looks fine" on screen, that does not mean text, edges, and fine detail in the original are approved. After downloading, inspect the original size; important files should be reviewed again on a larger desktop display when possible. The second is photo privacy. Only authorize and upload materials needed for this task, and do not test with client-sensitive images, identity documents, unreleased products, or persons not authorized for use.
