I tried wget with this but of no help. It just makes a particular file in jpeg format but on opening the same it says corrupted. Although I can edit the jpeg as an HTML file.

Code:
wget "http://www.google.com" -O /tmp/abc.png

Can someone please help me on this?

IMHO, using wget on a website is not the same as getting a screen shot. The best you can do, as far as I know, is to get all of the images, html, etc using wget -m. It is probably analogous to using internet explorer to save the website. Hence you will have a directory of all of the files that are downloaded with the site. You can also try curl, but it probably works the same way.

test::html::w3c

Test::HTML::W3C(3pm)					User Contributed Perl Documentation				      Test::HTML::W3C(3pm)

NAME

       Test::HTML::W3C - Perform W3C HTML validation testing

SYNOPSIS

	 use Test::HTML::W3C tests => $test_count;
	 # or
	 use Test::HTML::W3C 'show_detail';
	 # or when using both
	 use Test::HTML::W3C tests => $test_count, 'show_detail';

	 is_valid_markup($my_html_scalar);

	 is_valid_file("/path/to/my/file.html");

	 is_valid("http://example.com");

	 # Get the underlying WebService:;Validator::W3C::HTML object
	 my $validator = validator();

DESCRIPTION

       The purpose of this module is to provide a wrapper around the W3C that works with the Test::More testing framework.

ABUSE

       Please keep in mind that the W3C validation pages and services are a shared resource. If you plan to do many many tests, please consider
       using your own installation of the validation programs, and then use your local install by modifying the local validtor:

	 my $v = validator();
	 $v->validator_uri($my_own_validator);

       See the documentation for WebService:;Validator::W3C::HTML and the W3C's site at http://validator.w3.org/ for details

       validator();
	   Description: Returns the underlying WebService::Validator::HTML::W3C object

	   Parameters: None.

	   Returns: $validator

       plan();
	   Description: Access to the underlying "plan" method provided by Test::Builder.

	   Parameters: As per Test::Builder

       is_valid_markup($markup[, $name]);
	   Description: is_valid_markup tests whether the text in the provided scalar value correctly validates according to the W3C
	   specifications. This is useful if you have markup stored in a scalar that you wish to test that  you might get from using LWP or
	   WWW::Mechanize for example...

	   Parameters: $markup, a scalar containing the data to test, $name, an optional descriptive test name.

	   Returns: None.

       is_valid_file($path[, $name]);
	   Description: is_valid_file works the same way as is_valid_markup, except that you can specify the text to validate with the path to a
	   filename. This is useful if you have pregenerated all your HTML files locally, and now wish to test them.

	   Parameters: $path, a scalar, $name, an optional descriptive test name.

	   Returns: None.

       is_valid($url[, $name]);
	   Description: is_valid, again, works very similarly to the is_valid_file and is_valid_file, except you specify a document that is
	   already online with its URL. This can be useful if you wish to periodically test a website or webpage that dynamically changes over
	   time for example, like a blog or a wiki, without first saving the html to a file using your browswer, or a utility such as wget.

	   Parameters: $url, a scalar, $name, an optional descriptive test name.

	   Returns: None.

       diag_html($url);
	   Description: If you want to display the actual errors reported by the service for a particular test, you can use the diag_html
	   function.  Please note that you must have imported 'show_detail' for this to work properly.

	     use Test::HTML::W3C 'show_detail';

	     is_valid_markup("<html></html">, "My simple test") or diag_html();

	   Parameters: $url, a scalar.

	   Returns: None.
