Using CDHtmlDialog app, changing images (JPG,PNG) dynamically in the HTML Page

Hello all,

I created a MFC dialog using CDHtmlDialog and added a HTML page with many controls and one of them is a IMAGE tag. I got a default image loaded from the hard drive displayed in the HTML page. Up to this part, everything works fine.

Now what i want to do is, dynamically change the image based on the user click on one of the HTML buttons. I don't want this image source to be hard coded in the HTML nor the image source send from the MFC app.

What i want is for the MFC app to send the image data to the HTML in some (binary) format and then the page to display the image. 

The possible option i was thinking of was to read the image file which is already in my hard drive as a binary file and send the binary data across to the HTML as a memory buffer, and then use JavaScript to decrypt this binary data and display the image.

I am not even sure whether this is possible. So basically what i want is for the HTML page to display a image from the memory.

Can anyone guide me on how to do this? What approach needs to be taken?

Thanks in advance.
