we can use the name of the photo according to a variable of another question !

This makes no sense to me. The label of a variable is a comment for the data user. It is attached to the whole column of data - all establishments, with varying names.

This also makes no sense to Survey Solutions Designer, it will issue you an error:

[WB0008]:It is not allowed to use substitutions in variable label
