The plugin renames the photo. There are several renaming options available: using a counter and using the date/time (shooting or current)
The renaming pattern is set in the corresponding field in the settings. Example:
IMAGE_[COUNT]
with the number of digits 4, will output the file name IMAGE_0001.jpg
And the pattern: [YEAR]_[MONTH]_[DAY]_[COUNT]
will give 2022_05_18_0001.jpg
You can also create subdirectories automatically. For example:
[YEAR]/[MONTH]/[DAY]/[COUNT]
when saving the file, it will create a directory 2022/05/31 and the file will be saved with the name 0000.jpg
You can set the counter to 0 every time the plugin starts, or do it manually in the settings.
