You'll probably just need to write some code to clean the directory up yourself. You could also log a bug for this in the bugzilla at eclipse.org/birt.

Thanks Michael, but what if I have other files in the folder that I do not want to delete?

You could look for a pattern of the filename that BIRT creates. In an app I have running, these names are like "customNxxxxxxxxxxx.png".

Just spoke with a coworker of mine who has set something like this up. He said he pulled the metadata of the images and cleared all but the most recent one.
