linux下用socket，client向server传送图片

Question

可以实现字符串的传输，在向服务器传输图片存盘时，总是无法显示图片。下面代码是服务器和客户端传送图片的部分。求大神指定！
服务器端：
unsigned char recPhotoBuff[100];

unsigned char sendPhotoBuff[100];
char recPhotoPath[50];
char recPhotoName[20];
FILE *recPhotoFp;
FILE *sendPhotoFp;

///*
unsigned char ch;
recv(clientfd,recPhotoName,100,0);
recPhotoName[strlen(recPhotoName)-1]='\0';
printf("You get an image: %s\n",recPhotoName);
printf("change the name you want: ");
scanf("%s",recPhotoName);
//printf("\n");
sprintf(recPhotoPath,"/socketTest/photo/server/receive/%s",recPhotoName);
if((recPhotoFp=fopen(recPhotoPath,"wb+"))==NULL)
{
printf("cannot open image %s\n",recPhotoName);
return 0;
}
while((n=recv(clientfd,recPhotoBuff,100,0))>0)
{
recPhotoBuff[strlen(recPhotoBuff)-1]='\0';
ch=atoi(recPhotoBuff);
fputc(ch,recPhotoFp);

}//while
  fclose(recPhotoFp);
  printf("The image is saved!\n");

//*/

close(clientfd);
close(sock_fd);

return 0;

服务器端：
char sendPhotoName[20];

char sendPhotoPath[50];
char recPhotoName[20];
char recPhotoPath[50];
FILE *sendPhotoFp;
FILE *recPhotoFp;
unsigned char sendPhotoBuff[100];
unsigned char recPhotoBuff[100];
unsigned char ch;
while(1)
{
printf("please input the name of the image you want to send: ");
scanf("%s",sendPhotoName);
send(sock_fd,sendPhotoName,strlen(sendPhotoName),0);
sprintf(sendPhotoPath,"/socketTest/photo/client/original/%s",sendPhotoName);
if((sendPhotoFp=fopen(sendPhotoPath,"rb"))==NULL)
{
printf("cannot open image %s\n",sendPhotoName);
return 0;
}
printf("please input the name of the receive image: ");
scanf("%s",recPhotoName);
sprintf(recPhotoPath,"/socketTest/photo/client/receive/%s",recPhotoName);
if((recPhotoFp=fopen(recPhotoPath,"wb+"))==NULL)
{
printf("cannot open image %s\n",recPhotoName);
return 0;
}
while((ch=fgetc(sendPhotoFp))!=EOF)
{
sprintf(sendPhotoBuff,"%d",ch);
int b=atoi(sendPhotoBuff);
fputc(b,recPhotoFp); //在客服端存盘，此部分可以实现

send(sock_fd,sendPhotoBuff,strlen(sendPhotoBuff),0);
//usleep(1000);

 }//while !

fclose(sendPhotoFp);
fclose(recPhotoFp);
printf("The image is sent!\n");

} //while 1
//*/

close(sock_fd);

return 0;

建议你将发送的图片与接收后保存的图片的数据进行对比，看看有什么错误（不能显示肯定是有错误了）。
知道错误后，再来分析代码。
