Data URL scheme, include files in-line in the web page

There is a restriction in the blogger.com sites: you can't upload files.
The data URL scheme provides a way to include data in-line in web pages as if they were external resources.

The format of data URL:

data:[<mediatype>][;base64],<data>

Some examples:

• Image:   (If you don't see an image your browser does not support data URL)

<IMG

SRC="data:image/gif;base64,R0lGODdhMAAwAPAAAAAAAP///ywAAAAAMAAw
