PicSizer is a utility designed specifically to generate screen-friendly versions of high-resolution images. It offers a quick and intuitive way to resize images individually and in batches.
It was created with owners of digital cameras in mind, but it can also be very useful to designers and other people who work with images on a daily basis. PicSizer reads and writes several popular image formats, and outputs to any dimensions between 1 and 1024 pixels

I find picsizer a great little tool for resizing large batches of images into smaller sized images, which then fit nicer onto my websites.
There are a few options, you can determine the quality of the re-sized images and also which format you want them in.
All-in-all a great free tool which can save you plenty of time! :-D
