You try to attach a picture, but an app shows only a few older images while Photos still contains the full library. This does not establish that anything was deleted or that the iPhone is faulty. Limited access may explain the situation, but the app's selection method matters too. Avoid deleting the app or granting broad access just to get through one upload.
1. Find the picture in Photos first
Open Photos and locate the exact image. If it remains there, the immediate problem is selecting or sending it, not necessarily losing data. Use a harmless test picture rather than repeatedly uploading identity documents to different services.
Distinguish 'missing from the list' from 'selected but upload failed'. They require different investigations. Capture an error if useful, but avoid including the whole library in a support screenshot: small background thumbnails may reveal pictures you never intended to share.
2. Review the particular app's access
Choose the app in Settings > Privacy & Security > Photos. Limited access covers selected pictures; compare different labels with Apple's explanation.
If an option to edit permitted photos appears, add the image you need and try again. Sending one quotation picture is different from managing a library. Read the app's explanation before widening access. If your screen differs, check the iOS version and the app's help instead of guessing what an unfamiliar control does.
3. A system picker is not full-library access
An app can use the iOS system picker to receive your selected images without permission to read the whole library. Apple's PhotoKit documentation explains this distinction. Seeing many pictures inside that picker does not, on its own, mean the app has unrestricted access.
For a profile picture, try completing the task through the available picker first. Check whether the confirmation includes one image or several. A library manager or photo editor may have different needs. Evaluate the actual task instead of applying one blanket permission choice to every app on the phone.
4. A hidden album does not replace permission control
Apple notes that full access includes hidden photos even in a locked album. Check shared location metadata too; hiding pictures does not replace choosing appropriate access.
Changing permission later should not be treated as evidence that a recipient deleted an uploaded copy. Check the receiving service's deletion process when sensitive content has already been shared. Before sending a document photo, conceal unnecessary details and confirm the recipient rather than focusing only on the operating system's permission prompt.
5. Investigate the remaining error separately
Retry with a small, non-private image after adjusting access. If it appears but fails to upload, note the message, connection conditions and file type for support. Increasing permission repeatedly is not a universal upload repair: access and the receiving service's format support are separate concerns.
For unsupported files, read iPhone HEIF or JPEG for work sharing. The iPhone 15 Pro below illustrates an iOS device. Browse phones when comparing hardware, but an incorrect permission setting is not a reason to replace the handset.
Conclusion
Start by finding the photo, then review the relevant app and the access it actually needs. Grant only what suits the task, test with a harmless image and verify the destination before sharing. That is more practical than opening the full library to every application.
