A Python RFC2397 ("data url") implementation
The rationale behind this package is described in this blogpost.
Python 2.6 and 2.7, not tested on Python 3+ (yet).
$ pip install rfc2397
An executable named rfc2397 is then placed in the python environment that pip installs to.
As an alternate method, it’s also possible to copy the rfc2397.py file to any location and run the script stand-alone.
Just give rfc2397 a path to an image file. rfc2397 uses Python’s mimetypes module to determine what MIME-type a file has (N.B: the program won’t stop you from encoding something too large/an unsupported mime-type).
$ rfc2397 dot.png # <- your image path data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAIAAACQd1PeAAAADElEQVQImWP4o8oAAANCASIYayeeAAAAAElFTkSuQmCC
