How to use filename as a title for images in Gallery Block in 7.1 in 2022 ? Please and thank you.

I am trying to get a gallery block in 7.1 to display the file name as the Title.

I have "show title" ticked in Design panel.

I have tried some scripts from the forum, but they dont seem to work with 7.1

As I have hundreds of images to upload, i dont want to manually type the "Titles" in when the title is correct is the file name I upload. 

Any help, most appreciated.

With thanks

Adrian

You can try this code, if you haven't entered caption, the code will get file name as caption
