if you wish to embed images in html, web2py has a little know, but handy
function:
embed64(data, extension)
in your case you coud simply use:
<img src="{{=embed64(data=data, extension='image/png')}}"/>
without doing the base64 encoding yourself.
Embedding is very efficient for small images, can be bad for large ones
