Very simple site for resizing ~ it walks you through every step.
I use the same program as ShortcakesSweets. Don't know if that helps/matters.
Go to www.shrinkpictures.com.
Click on Resize.
Scroll down and type in wherever your pictures are saved (mine is My pictures). Click Browse.
That brings up the files with all my pictures. Choose the one you want to upload and click on it. That takes you back to the resizing page. Choose the size you need and click resize. When it is done resizing it puts up a pic of it. Right click on that picture and click on Save As. On that box click on save and it will save it to the same file your original picture is in. Then you just upload it.
Hope this helps.
For my pictures I bring up the one I want and right click on it. Then click edit. That brings me to another screen. In one of the top tabs there should be a place that says "stretch/scew". If you click on that one it takes you to a screen where you can change the percentage size of the pic. I usually do mine at 75% up and out.
I hope that all made sense.

If you are using Windows, Microsoft offers a free tool that will resize one, some, or all of your images. You can find it here: http://download.microsoft.com/download/whistler/Install/2/WXP/EN-US/ImageResizerPowertoySetup.exe
Once you download and install it, find the picture or pictures you want to resize, right click them (or highlight a bunch at one time and right click anywhere in the selection) and choose "Resize Pictures" You will get a few options that are self explanatory.
