What is Base64 and why it should be used to encode images?
Base64 is a group of encoding schemes to represent binary data in ASCII characters.Base64 is used, when binary data (such as images or video) needs to be transmitted oversystems that are designed only to deal with data in a plain-text format. Encoding imageswith Base64 system help to avoid data corruption when shipping it across network. Theprocess of encoding is done, by dividing binary data into 6-bit chunks and convertingthese chunks to the following 64 ASCII characters - 10 digits, 26 lowercase and 26uppercase latin alphabet letters, + and / signs.
When Base64 encoded images are useful?
As the web grows more complex, web performance is becoming anincreasingly important topic. One of the strategies to improve website performance isreducing the number of HTTP requests done for downloading first render resources. Aseparate HTTP request is sent for every image located on the web page. By using dataURI, which contains Base64 encoded image content, image file can be embedded in HTMLdirectly. So there will not be need to download an image and your website will speed up.However the wrong usage of data URIs can lead to performance lack for anumberof reasons.So it is recommended to use Base64 encoding for non-big images (up to 1 MB) and notoveruse them in web page.

- Base64-encoded data URIs are 1/3 larger in size than their binary equivalent. (However, this overhead is reduced to 2-3% if the HTTP server compresses the response using gzip)8 Data URIs do not carry a filename as a normal linked file would. When saving, a default filename for the specified MIME type is generally used.

The easiest way to install this is with Package Control.

- Select 'Package Control: Install Package' (it'll take a few seconds)
- Select Image2Base64 when the list appears.
Package Control will automatically keep Git up to date with the latest version.
Alternative
Create plugin folder in Sublime's user packages directory and copy all plugin files there. Then restart Sublime Text.
