Our solution will allow selecting 3 separator types: dashes, hyphens or underscores. You can select a separator under PicManager: Image Upload > Settings:
However, please, ensure that the selected separator is not included into the image name. For instance, If you choose '_' as the separator, a valid image name would be 'image_1.jpg' where 'image' does not contain '_'. An invalid image name would be 'image_name_1.jpg' where 'image_name' contains the '_' character.
To upload images in a specific order, you can use numbers after a separator (e.g., test_1.jpg, test_2.jpg, test_3.jpg). However, please, ensure that the selected separator is not included into the image name. For instance, If you choose '_' as the separator, a valid image name would be 'image_1.jpg' where 'image' does not contain '_' . An invalid image name would be 'image_name_1.jpg' where 'image_name' contains the '_' character.
As a result, the images will be matched to the same product:
And eventually uploaded in the required order:
