Sometimes, you find a drawing or similar image useful for a Wikipedia article, that was saved as a JPEG but should have been saved as a PNG.JPEG is good for images where the color changes fluidly throughout the image, like in a photograph, whereas PNG files are good for images with relatively few colors, such as a drawing of a flag, a chart, or a map; note that sometimes SVG is better.
Some PNG files will no longer auto-upsize to widths larger than the original, without causing the image to become skewed and blurry. Otherwise, PNG images still auto-thumbnail to smaller sizes and retain most of the clarity when smaller. All through 2008 and early 2009, JPEG images seem to thumbnail OK as well.
Images can often be improved – or even transformed – by using graphics software such as Photoshop or the free GIMP and Paint.NET applications. Many other programs also have photo-enhancing tools, including facilities for semi-automatic image enhancement, so that you need only click a button, or choose a thumbnail, to have a positive effect on image quality.
