i solving it like 80 % here is the code just trial code to show pictures from with sd card on website
//zoomkat 1/26/13
//SD server slider test code
//open serial monitor to see what the arduino receives
//address will look like http://192.168.1.102:84/servosld.htm when submited
//for use with W5100 based ethernet shields
//put the servosld.htm, slider.js, bluev_sl.gif,
//and bluev_bg.gif on the SD card
//files at http://web.comporium.net/~shb/servoslider.htm page

it worked good some how but when i press on ON button it lights the led but go to empty page so i must press back to the index.html
second problem the address now is 192.168.1.102:84/index.html i think it will make problem in port forwarding as i forward to port 84 only not 84/index.html how can i solve it ?
