2. JPEG
Stands for "Joint Photographic Experts Group." JPEG is a
popular image file format. It is commonly used by digital
cameras to store photos since it supports 224 or
16,777,216 colors.

3. JPEG filename extensions
JPEG compression are .jpg and .jpeg, though .jpe, .jfif and
.jif are also used

4. Syntax and structure
A JPEG image consists of a sequence of segments, each
beginning with a marker, each of which begins with a 0xFF
byte followed by a byte indicating what kind of marker it is.

5. Encoding
Most image software uses the simpler JFIF format when
creating a JPEG file. The common methods of encoding
when applied to an input that has 24 bits per pixel. This
particular option is a lossy data compression method.

6. Effects of JPEG compression
JPEG compression artifacts blend well into photographs
with detailed non-uniform textures, allowing higher
compression ratios.

7. JPEG Stereoscopic
JPS is a stereoscopic JPEG image used for creating 3D
effects from 2D images. It contains two static images, one
for the left eye and one for the right eye; encoded as two
side-by-side images in a single JPG file.

8. JPEG Multi-Picture Format
JPEG Multi-Picture Format (MPO, extension .mpo) is a
JPEG-based format for storing multiple images in a single
file. It contains two or more JPEG files concatenated
together.
