This characteristic sometimes results in a smaller file size for some lossless formats than lossy formats. For example, graphically simple images (i.e. images with large continuous regions like line art or animation sequences) may be losslessly compressed into a GIF or PNG format and result in a smaller file size than a lossy JPEG format.
Do not include the File: or Image: prefix, do not enclose the name in [[brackets]], but do remember to include the filename extension. image_upright should normally be left blank, so that the size defaults to the size set in a user's preferences. alt should be set to a description of the image for visually impaired readers. See WP:ALT. Do not ...
JPEG Stereoscopic (JPS, extension .jps) is a JPEG-based format for stereoscopic images. [ 61 ] [ 62 ] It has a range of configurations stored in the JPEG APP3 marker field, but usually contains one image of double width, representing two images of identical size in cross-eyed (i.e. left frame on the right half of the image and vice versa) side ...

Any or none of these options may be specified to control the size of the image. In the case of images with captions, if the image is already smaller than the requested size, then the image retains its original size (it is not enlarged). In the case of images without captions, the image will be enlarged or reduced to match the requested size.
The JPEG File Interchange Format (JFIF) is an image file format standard published as ITU-T Recommendation T.871 and ISO/IEC 10918-5. It defines supplementary specifications for the container format that contains the image data encoded with the JPEG algorithm.
The ability to read PNG images from ICO format images was introduced in Windows Vista. [7] A PNG image can be stored in the image in the same way as done for a standard Windows BMP format image, with the exception that the PNG image must be stored in its entirety, with its file header and must be in 32bpp ARGB format.
JPEG 2000 is slightly more space-efficient in handling natural images. The PSNR for the same compression ratio is on average 3% better than the PSNR of PGF. It has a small advantage in compression ratio but longer encoding and decoding times. [2] PNG (Portable Network Graphics) is more space-efficient in handling images with many pixels of the ...
