Windows XP users familiar with the picture resizer powertool which adds a basic batch picture re-scaling tool to explorer were upset to realize that the XP power tools don’t work with Vista.
The basic function offered by this tool was pretty handy. Enter the VSO Image Resizer, a completely free software tool that can re-scale a folder of pictures, save it as a JPEG, GIF, TIFF or BMP at the quality that you specity. The tool launches from the right-click drop down menu in explorer and offers simple and basic functions in an intuitive interface. For non-commercial use there is no cost for the software. It even works on Windows XP.
