hashed filenames in published output

if you are really precise, the filename is not a hash - it is independent of the content.

It is generated when the medium is imported - a GUID-4 is generated, e.g. 

• "06a3dc93-48e9-4ac5-97d2-cec1cd3df540"
  
  
• the guid is then split into its 5 blocks
• the last two blocks are removed
• the first three are put together backwards
• the whole thing is now converted to base62
• at the end, an “R” is added in front and the appropriate file extension is added
  
  
• result: "R5wlhTmswUhH.png"

if you now parse “story/story.xml” in the .story file, you can find out the mapping between the original file name and the generated file name
