I am trying to create a simple time lapse app for my N9.
The primary camera should take a photo every 10 seconds and save it to "hard disk".
The code below is working, the pictures are saved to /home/user/MyDocs/DCIM/img_%04d.jpg
But: After some time, depending on resolution and interval, the app (sometimes even the phone) freezes and does not respond anymore.
Watching the memory usage, I figured that the memory (RAM) continuously gets fuller while the app is running. It seems like the pictures are not just saved to file, but also are kept in memory, causing the app to crash.
Did I miss something?
Is there a better way to save the Pictures *without* keeping them in memory?
And how can I manually define file names / save locations?
How can I add EXIF information like GPS positions?

Here is my QML code:
