left – shifts the image to the left margin; right – shifts the image to the right margin; center – shifts the image to center between left/right margins; Each of the above sizing options can be used in any image link coded into a Wikipedia page, in the form [[File:Example.jpg|thumb|upright|left|Description]]. When a user views the page ...
The resulting image is larger than the original, and preserves all the original detail, but has (possibly undesirable) jaggedness. The diagonal lines of the "W", for example, now show the "stairway" shape characteristic of nearest-neighbor interpolation. Other scaling methods below are better at preserving smooth contours in the image.
Original image to be made narrower Scaling is undesirable because the castle is distorted. Cropping is undesirable because part of the castle is removed. Seam carving. Seam carving (or liquid rescaling) is an algorithm for content-aware image resizing, developed by Shai Avidan, of Mitsubishi Electric Research Laboratories (MERL), and Ariel Shamir, of the Interdisciplinary Center and MERL.
When scaling a vector graphic image, the graphic primitives that make up the image can be scaled using geometric transformations with no loss of image quality. When scaling a raster graphics image, a new image with a higher or lower number of pixels must be generated. In the case of decreasing the pixel number (scaling down), this usually ...
Resizing an animated GIF image will significantly reduce its quality, without any reduction of download time. When there are two or more "size" options of the same type, only the last one is valid. However, if both an upright and an absolute size are used together, the absolute size always takes precedence, regardless of where it appears in the ...
Adding such extraneous code will cause many infoboxes to break. Also, be aware that some infoboxes require that the file's name be placed without the file/image namespace prefix. Thus, and for example, if File:Name.jpg does not work, try just Name.jpg.

Always work from the original image and not from the already saved JPEG file, as quality gradually decreases the more you save it; this is known as digital generation loss. For this reason, it may be good to keep the main copy here in a lossless format like a raw image format or PNG. However, as of right now, scaled versions are forced to be in ...
