Legal validity of photos via Zoho Expense

A question arises with regard to the dematerialization of expense claims.

A question arises with regard to the dematerialization of expense claims.
Are photos taken with the Zoho Expense application legally valid? Is there a code that is assigned to each photo to verify the authenticity of the photos? Like Zoho Sign.
(We are in France).

Thank you in advance
