web page input to C++ code

hi all

I have a web page that contains a button. on click of this button an image is loaded from my hard drive.
I want to send this image as the input to my C++ exe file.
Any pointers as how to do this.
Any documentation for the same would be of great help.

Thanks

 

I didn't get the idea very clearly ...

(1) Do you want to send the path of the image as input into your C++ exe or something else ???
(2) Do you want to send it, when the button is pressed ?

Please, be a bit more clear.

 

Thanks for your reply.
I need to send whole image as input to exe file.
