I cant think of any other way to display the photos Eric.
The program extracts a list of images in the selected folder and presents them alphabetically.
As you know, at that stage they are not linked and "unknown" to the database.
Other options I could provide wouldn't be useful - e.g. file size, date.
You really do not need to rename your images. The software will provide a more accurate listing of the folder contents if the file names are as assigned by the camera - i.e. in sequential order.
If you do prefer to rename them, heres a suggestion:
Alphabetically, 1, 10 and 100 come before 2 and 20
Instead of naming them 1, 2 ,3, name them:
001, 002, 003 e.g. through 010 and up to 100 (assuming your folder has less than 999 images).
If more that 999, then they need to be:
0001, 0002 etc
They will then align properly in the program.
Does that help?
