Yes. You might need to use content.tostring() - I am not familiar with
MySQL blobs.

Dear Victor:
If you cannot understand, after being told several times by different
people, that pages with images in them are achieved by multiple HTTP
requests, then there is little I can do to help you.

You can say it as clearly as you like, but if you say it too loudly you
will make a laughing stock of yourself.
You surely don't think that a language that supports Zope, TurboGears,
Pylons and Django (to name but the first four that come to mind) is
unsuitable for web programming?
Please, do yourself a big favor and persist with this until you
understand what you are doing wrong and how to serve dynamic images. It
appears that the learning may be painful, but I guarantee it will be
worthwhile.

Steve
