Hi barneyhairball,
Welcome to the Apple Support Communities!
I understand that you and not seeing photos on My Photo Stream that you took with your iPhone camera. My Photo Stream does not use iCloud storage, so this should not be the issue. To begin troubleshooting this situation, I would recommend reading over and working through the information located in the attached article below.

I don't see photos from My Photo Stream on my iPhone, iPad, iPod touch, or Apple TV
If you’ve turned on iCloud Photo Library, every photo and video you take will live in iCloud, including ones from your My Photo Stream. If some of your devices don't have iCloud Photo Library enabled, My Photo Stream will upload your recent photos to share with those devices.
If you can't find your My Photo Stream images in the Photos app, follow these steps:
- From the Home screen, tap Settings > Wi-Fi. Make sure that Wi-Fi is on, and that you have an Internet connection.
- Go back to Settings and tap iCloud > Photos.
- Make sure that My Photo Stream is on. If it’s already on, turn it off and tap Delete. Then, turn on My Photo Stream again.
- On the device that took the photo you're looking for, close the Camera app. Nothing uploads to My Photo Stream until you do.
- See if your iOS device is below 20% battery power. If it is, My Photo Stream will be disabled temporarily to preserve battery life.
If you're using an Apple TV, it might display only your most recent photos due to its storage capacity.
Best regards
