There _is_ a way to embed image data in HTML that is supported by every major browser. It is ugly. Using the RFC 2397 (http:// www.ietf.org/rfc/rfc2397) spec for data URLs you could go '<img src="data:image/jpg;base64,%s">' % base64.b64encode(image_data) Obviously you need to import the base64 module somewhere in your code and base64-encoded data is about a third larger than it would be otherwise, so embedding anything particularly large is going to be a huge pain and affect page load times pretty badly. -- http://mail.python.org/mailman/listinfo/python-list
