Alignment of HTML export in org-mode with babel/ditaa-generated image

[unfrostedpoptart <david@therogoffs.com>]

There's way too much going on here for me to follow with my limited knowledge of babel, ditaa, and org-mode export.

I created a block diagram in a babel source block in my org-mode document.  I then export as HMTL.  babel runs java on the code which create a png file. Then the HTML file is created, which references and displays this png image.  So far, so good.

However, the image is always centered in the HTML.  I want it left-aligned but can't figure out who I tell (html export?) and where I put it so get this passed into the HTML.

Any pointers?

Also, how do I get babel not to ask me every single time I export to HTML if it's OK to run the java code?

Thanks,

 David
