Note: For resizing and posting or e-mailing many images at once, see: How to Easily Resize Images in Windows
There is another little problem I see a lot: How does one resize and/or crop an image to a specific custom pixel size in order to post it online somewhere, or to send in an e-mail, or whatever?
Of course, most online services and social networking sites will automagically resize and compress your images for you, and the they often even let you crop the image right there on their site.
But, sometimes you need to create an image of a specific size, like when creating a Facebook-friendly image.
Fortunately, it turns out that there is a fairly easy and completely free way to do it without any extra software!
