the image attachment cannot be lightbox effact?

Hello,

Please take a look at this link https://www.extendoffice.com/documents/excel/3151-excel-shuffle-rows-cells.html

when the user click on the image, it will just go to downlaod it? Why can it be lightbox to view it?



Where can i configure it? Please show me the trick.

If there is no such feature, How can i modify the templace file to get it?

Please don't just answer me for the ftp access.
