How to Edit Images in MS Paint

Sometimes, the best tools are the simplest. MS Paint is a very basic (read: oft-ignored) application that has evolved over the years not just for sketching and painting rudimentary drawings, but as an image-editing tool as well.
So the question becomes, "In the prevalence of sophisticated programs like Adobe Photoshop gaining widespread use, why bother with such an inferior application?"

One strong argument for using MS Paint is that it is pre-installed on every computer that runs Windows. You need not stumble around an unfamiliar application when on someone else's system, or spend hundreds on multiple licenses getting your favorite editor on more than one computer. Just open good ol' Paint and away you go. Also, it is free. With photo editors easily costing in the hundreds of dollars, and professional editions priced higher yet, a free program is always a welcome addition to your bag of tricks.

1) Resize a Picture - Open a picture in Paint. Move the mouse to the toolbar, and click on Image. Select Stretch / Skew. A box will appear labeled "Stretch". By the "Horizontal" and "Vertical" textboxes you can enter any number form 1 to 500. If you enter "50" for the width, your picture will be 50% narrower. Entering "500" will make it 500% wider, and so on. Just make sure to enter the same percentage for both Horizontal and Vertical adjustments to keep the picture from getting too distorted. This is especially useful for those extremely large photographs that do not fit on the screen, and manually stretching or shrinking it would be more difficult.
