分享菜鸟，请教CGI向网页输出图像问题
void printImageResponse(const char *path)
{
fprintf(stdout,"Content-Type:image/jpeg\r\n\r\n");
FILE *fd;
int rc = 1;
int res = 0;
char buf[1024];
fd = fopen(path, "rb");
if (fd == NULL) {
fprintf(stdout, "open file error\n");
}else {
while(rc >= 1) {
memset(buf, 0, sizeof(buf));
rc = fread(buf, sizeof(char), MAXLEN, fd);
if(rc >= 1) {
fprintf(stdout,"%s",buf);
}
}
fclose(fd);
}
}
printImageResponse（“/root/ww.jpg”）;通过网页调试可以看到respose已经接收到数据，都是乱码，怎么样才能让他显示成一幅图像
