socket problem

Hey everyone,

I am doing an image server project. The image format is *ppm(Portable
Pixel map). When client request a image to server, server store a
iamge into a data structure ,called pixarray. The pixarray contains
entire image info. How can I write it to socket and client read it
from socket by using write() and read()? Because I could only handle
text under the argument of socket functions read(int client_sock,char*
text, int size) and write(int server_sock,char* text, int size).

Thanks,
