send image using wifi shield

Hello every body,
I'm using arduino Mega 2560 with an arduino wifi shield, my application is to send image with HTML code stored in the SD card (on the wifi shield) to a Laptop , but the problem is the browser respond after a long time and hardly can show the image , any idea about this, and thank you for help

and hardly can show the image

It either can, because the data was sent properly, or it can't, because the data was not sent properly. There are no degrees of success.

any idea about this

There are several things that you might be doing wrong. Not posting code is the easiest to fix.

You should also specify which WiFi shield you are using.
