here's a refresher course:
before adding applications for resizing, check to ensure you don't already own the equivalent.
right click on your image.
if it's an image you own, you'll have an option to "open with". Fly over this and see what your options are.
you might see software you loaded when you got your digital camera.
you might see a photo editor (or two) you didn't even know you had.
you might see microsoft photo editor (this would be the best choice).
any of these will have a resizing tool that is easy to use. normally it will be found under the "image" tab in your editor or organizer.
you may have an option to change from inches.
make the larger dimension no greater than 750 pixels. (height or width) dial up users won't love you, but they won't hate you.
vista users can use "paint" for resizing, the new version has that tool, works on percentages , check the size of your edited image by right clicking on it and opening "properties", you'll then have a feel for the percentage you need to use.
Here is an easy resizer for XP…free:

Here’s the equivalent for vista…a tad more laborious:

when you close the application, you'll normally be asked if you want to "keep the changes to such & such". if you say yes, the image will be replaced with your new (resized image). you find it right where it was before.
if you wish to have both images saved, the resized as well as the original size, you'll need to save the new (resized) one.
