I don't doubt that making some sort of bkBrochure GUI is probably the way to go.
At this time thats way above my pay grade.
I understand what you are saying and I can now see these < > brackets are markup tag indicators.
Either way the markup for <img src= falls over because it does not know how to handle a .dds file when the <cover src= handles the same .dds file.
I like the idea of a bkBrochure and I can see how that could be extended to make a bkPostIt and a bkScribbledNote a bkMap and a bkSketchPad.
I might add all of these are also above my pay grade.
One of the options I would see the bkBrochure having is a back cover at present a book or a notebook finishes on the last page with an entry but a brochure quite often uses the back as more space for advertising.
As I say for now I have a work around using posters. I figured I had to have the pages somewhere in the age so I may as well have them visable rather than having them hidden.
At some point we are going to need linking books anyways.
Having a sound file attached takes me back to the original idea and it has allready been done. I am thinking here with the note in the cleft.
Ok this is a one page affair but it does show the concept holds water.
