As a web designer, I am sent images for websites in all sorts of shapes, sizes, and resolutions.  I would be absolutely lost without WinWatermark software.  Although not all my clients want their images watermarked, I find that resizing and renaming a batch of images just doesn't get any easier with WinWatermark.  Renaming images might seem time-consuming to some folks, but to me it's an important component of optimizing a website for the search engines.  The time saved using WinWatermark means I can spend more time obtaining more clients.
