this will take a image from C328 serial camera and store those images in mbed flash as html and this html page is uploaded into the server at ip:192.168.1.2

// Written by IVA2K
//
// Example of HTTPServer with additional features:
// * SNTP Client (Simple NTP)
// * Link status indication (LED4 or RJ45 socket LED on MBED-BoB2-mod)
// * Local file system (create index.htm page on MBED!)
// * SD-based WebServer
// * RPC-able class (myrpc, allows remote function call that blinks LED1 N times)
// * Static HTML page
// * Dynamic HTML page
//
// Instructions:
// 1 Plug MBED into MBED-BoB2 (or other ETH connector breakout)
// 2 Plug ETH connector into your network (needs DHCP to get IP address and Internet connection)
// 3 Power up MBED using USB cable
// 4 Install MBED serial driver (http://mbed.org/handbook/SerialPC)
// 5 Copy compiled .bin to your MBED (make sure target device selected in the compiler is correct)
// 6 Open terminal on the mbed serial port
// 7 Push MBED reset button
// 8 Terminal will display info message with mac address, followed by IP address (if connection succeeds)
// in the following items, replace 10.0.0.321 with actual MBED IP address from the terminal
// 9 Open browser and enter the following URL:
// http://192.168.1.2/rpc/myrpc1/blink,10
// 10 MBED will blink the LED 10 times
// 11 Open browser and enter the following URL:
// http://192.168.1.2/rpc/myrpc1/gettime
// 12 The browser will show date and time from the MBED synchronized to NTP server
// 13 Open browser and enter the following URL:
// http://192.168.1.2/static.htm
// 14 The browser will show static HTML page
// 15 Open browser and enter the following URL:
// http://192.168.1.2/dynamic.htm
// 16 The browser will show dynamic HTML page
// 17 Create a simple index.htm page on the MBED
// 18 Open browser and enter the following URL:
// http://192.168.1.2
// 19 The browser will show index HTML page
// 20 Create a simple index.htm page on a micro SD card, plug the card into MBED-BoB2
// 21 Open browser and enter the following URL:
// http://192.168.1.2
// 22 The browser will show index HTML page from SD card
// 23 Optionally, create file "sntp.ini" on MBED or SD card. Copy-paste SNTP configuration from the terminal into this file and modify to your needs.
//
// Notes: there are still some bugs in HTTPServer code.
// To help fight some of them, copy a valid favicon.ico (a 16x16 icon) file to MBED.
