I guess there are many ways to resize. I use irfanview. Here is the website
http://www.irfanview.com/ It's a free download. Once you have the icon on your desktop, drag the icon for your pic (you just copy it to your desktop) into the open box, go to 'image' and down to resize, I use 435, and save. That's it...very simple, because that's all I can handle.
