step 2:

I have updated the testscript as follows:
ChromeOptions options = new ChromeOptions();
options.addArguments("load-extension=C:\\Users\\pgudi\\AppData\\Local\\Google\\Chrome\\Application\\35.0.1916.114\\Extensions");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
oBrowser=new ChromeDriver(capabilities);

and in this path
C:\Users\pgudi\AppData\Local\Google\Chrome\Application\35.0.1916.114\Extensions
I added the following files (Manually)
i.icon.png
ii.manifest.json (this file inturn has the following lines
{
"name": "My First Extension",
"version": "1.0",
"manifest_version": 2,
"description": "The first extension that I made.",
"browser_action": {
"default_icon": "icon.png"
},
"permissions": [
"https://preview.dentalweb.com"
]
}
iii. external_extensions.json (this file exists bydefault,it has the
content as follows

// This json file will contain a list of extensions that will be included
// in the installer.

{
}

After performing above settings
I started running the script to capture screen shot,it works inconsistent
approach some time(in the same package) it captures screen shot and some
time (other package)it displays the following
exception
