Re: Export ascii-images using ditaa when targeting HTML?

[Sebastian Rose <sebastian_rose@gmx.de>]

Hi Eric,


yes, this looks fine to me and works :-)

What do the others think?

I believe overwriting is the desired behaviour on export. I use
org-publish-attachment for images, stylesheets, scripts and so on. And
they shurely should be updated in the publishing-directory.

I just wonder, why I never ran into that problem. All the other files
where always overwritten.



One more:

If I refile an entry containing such an ditaa image, the old image
remains in both, the base-directory, and the publishing-directory. An
option to set the image directory relative to base-directory (and adjust
the link accordingly) would be very nice. That way, we could refer to
the image in other files too and the links would work after refiling
such an entry.



Thanks again,

   Sebastian
