To calculate new image dimensions so that it's resized to a certain number of megapixels. Useful for determining maximum size for a non-free image thus keeping it within the guidelines
1) Enter current image width & height in the "CURRENT" column.
2) Press "Resize". New image dimensions will appear in the "RESIZED" column.
You can also change the target pixels (approx total number of pixels in the image). The default is 100000 (0.1 megapixels) which is usually just right for a non-free image.
