Is it possible to display dynamically updated pictures or PDFs in confluence?

[Eckhard Lanzinger]

Is there a way to display graphs that are automatically updated by some other system, e.g. by a cron job on a daily basis, on a confluence page?

Right now, I can only upload the new version manually and it would be great if this could be automated or loading the updated document could be performed on demand by clicking on a link or so...
