I am writing a Dutch manual & workshop.
When looking at the possibilities that galery offers with hires, i wanted to see more pictures than displayed on the page.
The solution I found is to define more pictures located on the same place ase the two pictures on the page. Only the height of the area I changed to 10.
So now, when I click one of the pictures two on the page in my book, I can navigate trough 10 pictures in Hires all belonging to the same galery.
Example:
<area left="75" top="195" width="255" height="160" hires="data/zoom1.jpg" gallery="hmr" gallerybutton="true"/>
<area left="75" top="385" width="255" height="160" hires="data/zoom2.jpg" gallery="hmr" gallerybuttonpos="top" gallerybutton="true"/>
<area left="75" top="195" width="255" height="10" hires="data/zoom3.jpg" gallery="hmr" gallerybutton="true"/>
<area left="75" top="195" width="255" height="10" hires="data/zoom4.jpg" gallery="hmr" gallerybutton="true"/>
