Hi, 

I have images from a construction camera that does not print EXIF data or the date/time taken. The images are numbered 0 - 2001 so in LRT 4.7.5 i see the images import as 

0
1
10
100
1000
1001
1002
1003
1004
1005
1006
1007
1008
1009
101
1010

Because i dont have the date and time information LRT automatically ticks the "sort by filename" box and i cant uncheck it. How can i get my images imported in a numerical order.

I did see another post, but this does not apply to me as i dont have date and time information.

Many thanks

That's indeed ugly. Bad design from the manufacturer of the camera using names that do not sort alphabetically.
I guess you'll have to find a renaming tool that batch renames those files to 00001, 00002 etc... maybe you could even use the renaming tool in Lightroom/Bridge to do this.
I'm sorry but LRTimelapse expects either Exif (given for 99,9% of all cases) or alphabetical filenames as fallback.
