When you are posting images in blogs or forums, You like to have a watermark on them. So that all know its been uploaded by you. If you are running a blog or a website, You use this to prevent copying. Even if someone copies he’ll be advertising for your site. 
There are many utilities available to watermark images. Very few are free and this is one of them. The actual application size is just 24KB. When I downloaded this I thought it’ll be a junk program. But then it’s coded with .NET. It’s small and serves my purpose. Remember that it’s a simple watermarker. You can change font, font size, bold, italics and underline text. You can change the position of watermark and its rotation.
