First, open your browser.
Now, type in the url of the page from which you want an image, and click Go.
Maximize the window, if it is not already. (If the middle box is a double box, then you do not need to do anything here).
Hold either Alt key on your keyboard, and click Print Screen at the same time.
Now, you will have a graphic copy of that page on your clipboard.
To get this to your webpage, open your image editor.
When a blank canvas is open, click Edit Paste.
The webpage should appear.
Save as gif or jpg…you may very well want to resize the image.
Once you are finished, upload the image to your server.
To link to the image, use <img src=imagenamehere.extensionhere(gif or jpg)>.
