    // tricky bit: Builds one full line for the vcard: vcard entry + base64 encoded file.
    // we need to split this unique line into 76 characters long.
    // BUT except the first line, all other have to be <space>+75 characters !
    
    // Builds the lone line.
    // note we insert 'HOTO' instead of PHOTO, because the following foreach loop
    // will add a space even on the 1st entry of the array
