Importing a folder of files all at once
Hmmm, your data only shows file names, not the location where they will be found. That requires a file path. If the path to that enclosing folder is known, you have two options:
You can use the method that DavidAnders is recommending to import all your images into a table and then import your text file with the image names imported into text fields. Relationships can then be used to link those records to your table of imported images by file name.
Or you can import the text file dat into text fields and use that known file path plus the file name to set a $Path variable to the file path and then a "by reference" image can be inserted into a container field.
Either way, I'd recommend setting up one table with the ID and another with one record and one container field for each image.

That's got the images linked to the file text file.
