If you are shooting 5MP jpg + 16MP jpg (16;9) or 5MP jpg + 19MP jpg (4:3) then each and every pic has 4 files, not 2.
WP_YYYYMMDD_HH_MM_SS_and one of 4 extensions. This breaks down to WP for Windows Phone/The Year in 4 digits/The Month in 4 digits/The Date in 4 digits (or date and then month under certain Region formats)/The Hour in 2 digits/The Minutes in 2 digits/and The Seconds in 2 digits.
So if I take a picture right now I get WP_20141007_10_30_27, the local date and time I'm writing this...
One pic makes the following files:
- WP_20141007_10_30_27_Pro.jpg
- WP_20141007_10_30_27_Pro.mp4.thm
- WP_20141007_10_30_27_Pro.mp4.tnl
- WP_20141007_10_30_27_Pro_highres.jpg
The 5MP is the first file and the 16(19)MP is the fourth, obviously. The second ending .thm is the animated Living Image. The third file is the one I want to ask about. The file that ends in .tnl is the thumbnail data for the package...
Are you stripping out the .tnl file from the Camera Roll???
Maybe you are/Maybe you are not... I'm pretty sure the .tnl points to the .thm file by default and then once the Living Image rolls out it puts up the 5MP by default.
At a guess if you want just the 16(19)MP pic to show you need to edit the .tnl file.
Off Topic: Did you know you can put the .thm files on your computer and edit off the ending in Properties so it says WP_YYYYMMDD_HH_MM_SS_Pro.mp4 and the Living Image now plays in your favorite video player?
