PhotoScale! Download
PhotoScale is a picture resizing and format changing tool. It can scale all the images inside a directory to a defined resolution quite quickly. It's pretty useful for users of social networking and photo sharing sites. It's an ideal tool when you have to upload to the web huge amounts of pictures. Most social networking sites use quite low image resolutions and uploading 3072x2304 (7 megapixels, approximately 4.5 megabytes) pictures is both a waste of time and bandwidth.
