Most of the utilities in NirSoft Web site allows you to create a simple HTML report containing the data that you need.

But what can you do if you want to get the report as image file ?

SiteShoter utility can help you do that.
SiteShoter is a utility that allows you to save any Web page or HTML file into image file(png/jpg/gif). Simply type the html file path in the URL field, choose all other parameters according to your needs, and then click the start button. It also recommened to set a low timeout value, because HTML files (As opposed to Web sites) are loaded pretty fast. If everything works fine, the image of your HTML file should be created in the location you specified in the 'Filename' field.

In the above example, you can see in the screenshot, the report.html filename will be saved into .png image file named 'report.png'

SiteShoter can also create images from command-line, for example:
SiteShoter.exe /URL "c:\temp\myreport.html" /Filename "c:\temp\myreport.png"
