INFRAVIEW is another popular resizer so I thought I would add that to this. Personally I find Faststone to be easier but there is more than one way to skin a cat.

First, Select FILE then OPEN



Choose the file where the pic is located



Select your pic and click OPEN



Select the IMAGE tab and click RESIZE/RESAMPLE



Here there are 2 methods of resizing. First, you can enter a pixal count and it will calculate the other side for you. Or, you can choose from some premetermined settings. Click OK when finished



Select the FILE tab and then SAVE AS



Here you can change the name of the file if you want to retain the original size as well as the new size.
