There are two completely different versions of this problem and they have nothing in common. On an iPhone, Phone Link photos are not broken, they were never there. On Android they do work, and when they stop it is almost always one of five things. Find your case below.

The quick answer: if your phone is an iPhone, stop looking. Phone Link has no photo transfer for iPhone, only calls, messages and contacts. If your phone is Android, the usual culprit is battery optimisation putting the Link to Windows app to sleep. Set it to Unrestricted and photos usually come straight back.

If you have an iPhone, the answer that saves you an hour: there is no photos feature to fix

This is worth stating plainly because almost nothing online does:

On Android photos do work, and battery optimisation is the reason they usually stop

If photos worked once and then quietly stopped, this is the first thing to check and the most likely answer:

Android per-app Battery settings showing Unrestricted, Optimised and Restricted, with Restricted currently selected
The setting to change, shown here on Restricted, which is the worst case. Unrestricted is the one that keeps Link to Windows awake in the background.

The permission that breaks it without any error message

Android permission dialog asking to allow Link to Windows to access notifications and photos and media, with Allow and Do not allow buttons
This is the prompt that decides whether photos ever appear. Tap Don't allow, or miss it, and Phone Link still connects while the photos panel stays empty.

What Phone Link is genuinely good at, and where it is the wrong tool entirely

A route that works from either phone, without a background service to keep alive

If what you actually want is specific photos on your PC, rather than a mirror of your recent camera roll, there is a more direct way, and it works the same on an iPhone as on Android.

Common questions about Phone Link and photos

Why does Phone Link not show photos from my iPhone?
Because the feature does not exist for iPhone. Phone Link's photo transfer works with Android phones only. Its iPhone support covers calls, messages and contacts, and there is no photos panel for a linked iPhone, so no amount of reconnecting or reinstalling will produce one.

Why have my Android photos stopped appearing in Phone Link?
The most common cause is Android battery optimisation putting the Link to Windows app to sleep in the background. Set that app to Unrestricted battery usage. After that, check it still has permission to access photos and media, and that both devices are signed in to the same Microsoft account.

How do I get a photo from my phone to my PC when Phone Link will not do it?
Use a direct transfer over your local Wi-Fi instead. Camera to Clipboard works from both iPhone and Android, puts the photo straight onto the PC's clipboard so you can paste it, and does not depend on a Microsoft account or a background service staying awake.
