I tried the free one from Microsoft that's one of their Power Toys that were
developed by some of their staff but not supported and are free to everyone.
It's very limited and after the quick install you can right click the mouse
and click on Resize and you get three options to choose from
Large, Medium and Small
It's great if your pictures came out too big and you want to send them to
someone in an e-mail. Click the link below to download it.
