Are you tired of making and merging images together to have a single image which shows the entire web page? Here you can now, take a breath.
There is a software namely, WebShot, which enables you to capture full size or thumbnail screen shots of web pages and save the resulting image in JPG, PNG, GIF or BMP format.
You can either capture the entire page (fully scrolled) in full size or tweak the browser window and resizing settings to create a thumbnail image of the site. WebShot can capture web sites based on a single input URL, or you can load URLs from a text file (one per line) and batch process the list of sites in a single run. A command-line interface is also available for advanced users.
This is a freeware so, you can use it free and for the lucky it is so small application viz, it only 557 KB in size. So, here I am going to give you the location to download.
