Delphi Firemonkey XE8 - how to correctly send/receive images using DataSnap

I'm developing an Android app using Delphi Firemonkey XE8. I need to send images to the server, where a service has to receive and store them.

So far I was able to send and receive simple classes, like this:

TCliente = class
        private
          pCodigo: integer;
          pNomeRazaoSocial: string;
          pApelidoFantasia: string;
          pCPFCNPJ: string;
        public
          property Codigo: integer read pCodigo write pCodigo;
          property NomeRazaoSocial: string read pNomeRazaoSocial write pNomeRazaoSocial;
          property ApelidoFantasia: string read pApelidoFantasia write pApelidoFantasia;
          property CPFCNPJ: string read pCPFCNPJ write pCPFCNPJ;
end;

The bitmap images are stored in a SQLite database as BLOB. I need to send those images to the server and, as soon as they get there, save them in the MySQL database, in BLOB fields as well.

I need to do it using DataSnap.

Everything I tried so far hasn't worked.
