The base64 Encode Images plugin for Coda 2 lets you quickly and easily base64 encode and imbed in images into your HTML or CSS files. Simply select the full path and image in your code, then select 'base64 Encode Image' from the Plug-ins menu (or use the keyboard shortcut 'Cmd + Ctrl + Shift + E') to automagically replace the path/image with the base64 Encoded image.

Note: In order for this plugin to work you must have the Local Root for your site correctly configured in the Coda Sites setup panel.
