is about the JPEG (Joint Photographic Experts Group) photographic file format. The JPEG format has become popular because of the capability to compress images and thus obtain high-resolution images at relatively moderate file sizes. The compression, however, involves loss of information and so when images are compressed down to a ration of 10:1 noticeable losses become apparent. JPEG is designed as a photographic format and is not well suited for line diagrams etc. with sharp contrasts since the compression algorithms may introduce artifacts.

Notice that `latex` is not able to import JPEG files unless they are embedded in an EPS file, while `pdflatex`, `xelatex` and `lualatex` can use them out of the box with the usual `\includegraphics` command.
