 If you want to do 2. there is no problem your application should
 display documents like this
 /browswer/<document_id>/<start>.html

 Then after conversion put all generated files in database, converted
 document (start.html) should be relatively linked, if some browser will
 call to load image big/my_logo.png, then it will do request
 /browswer/<document_id>/html/big/my_logo.png

 Your CGI/Servlet will capture every request after /browser, you have id
 of document and requested file name passed in URL then do
 SELECT content where doc_id=... and filename='....'

 Caching, speed-uping, on demand generation, securing is on your side.
