images in db

[Cornelius Jaeger]

Hi Jenna, Roland

Thanks for your responses.
How can I get the image inline in the html, rather than downloading it  
to the user?
I'm not at all sure how to use markaby to stream the image data into  
something the img tag will understand.
Many Thanks for helping

Cornelius
