Q: Photos don't appear in folder

G'day vincefrommartinka, 

Thank you for using Apple Support Communities. 

I understand that since you've updated your iPhone to iOS 9, you're unable to download photos to your PC. This is also preventing you from seeing photos that are older than one day. 

Use the article Import photos and videos from your iPhone, iPad, or iPod touch to learn how to transfer photos from your iOS device to your PC, specifically, this section: 

Import to your PC

You can import photos to your PC by connecting your device to your computer and using Windows Photo Gallery:

1. Connect your iPhone, iPad, or iPod touch to your PC with a USB cable.
2. You might need to unlock your iOS device using your passcode.
3. You might also see a prompt on the iOS device asking you to Trust This Computer. Tap Trust or Allow to continue.

Then, follow the steps in these Microsoft knowledge base articles to learn how to import photos to Windows Photo Gallery:

• Windows 10 
• Windows 8
• Windows 7

When you import videos from your iOS device to your PC, some might be rotated incorrectly in Windows Photo Gallery. You can add these videos to iTunes to play them in the correct orientation.

Photos and videos that you sync from your computer to your iOS device using iTunes can't be imported back to your computer. 

Learn what to do if you can‘t import photos from your iPhone, iPad, or iPod touch to your computer.

Additionally, you can use the article Check your storage on your iPhone, iPad, and iPod touch and go to Settings on your iPhone to see how much storage you've used.

Best Regards.
