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.
The image syntax begins with [[, contains components separated by |, and ends with ]].The [[and the first | (or, if there is no |, the terminating ]]) must be on the same line; other spaces and line breaks <br> (or <br />) are ignored if they are next to | characters or just inside the brackets.

The JPEG filename extension is JPG or JPEG. Nearly every digital camera can save images in the JPEG format, which supports eight-bit grayscale images and 24-bit color images (eight bits each for red, green, and blue). JPEG applies lossy compression to images, which can result in a significant reduction of the file size.
The capitalization in the wikicode must be followed; thus if an image file is Image:Photo of Wikipede.JPG, you will need to use the capital letters for "JPG". The image is blacklisted on MediaWiki:Bad image list .
To make your uploaded file appear in an article, you need to insert it: edit the article and add the syntax [[File:Image name|thumb|Caption]] where you want the file to appear. Important: Image names are case-sensitive. For example, if an image is called Picture.jpg then neither picture.jpg nor Picture.JPG will find it.
[1] A number of vector graphics editors exist for various platforms. Potential users of these editors will make a comparison of vector graphics editors based on factors such as the availability for the user's platform, the software license, the feature set, the merits of the user interface (UI) and the focus of the program.
The JPEG standard used for the compression coding in JFIF files does not define which color encoding is to be used for images. JFIF defines the color model to be used: either Y for greyscale, or YCbCr derived from RGB color primaries as defined in CCIR 601 (now known as Rec. ITU-R BT.601), except with a different "full range" scaling of the Y ...
