I’m an avid fan of android tablets. However, it will not be a perfect gift for my wife since she loves iPad more.

To make sure that my example works properly (it always works properly though), I will write a server side function which accepts the upload images. The server side functions will be implemented by PHP, a very simple script language. After that, I will write another tutorial for upload images from gallery or camera in iPhone and iPad.
