Hi Nagesh,
First, the reason why charts in an e-mail do not work, is that charts are SVG (vector) images, and not many e-mail programs will render those correctly. Not to mention that there's probably a lot of JavaScript needed, and no sane e-mail program will run JavaScript.
Secondly, you are confusing some stuff. First, you need to save the chart server side, not client side as I assume you mean by "save the chart [to the] hard disk". However, this is not easily done (see below). Also, you talk about "images folder in Service Studio", but the images in Service Studio can only be added design-time, not run-time. However, the images end up in the /img directory, and are accesible via eSpaceName/img/ImageName.jpg, so if you can save the image server-side, you need to put it there.
The only way to save charts server site, as far as I know, is to use server-side rendering code like PhantomJS. But unless you are well-versed in JavaScript and C#, that's not going to be easy (you need to create an extension etc.). You may be able to use the Forge component Html2PdfConverter, but that seems to have problems with HighCharts charts, and I'm not sure it can output images instead of PDFs.
