For a project I'm working on, I need to show html pages that are
stored in a database.
Showing these pages is not so hard ... wxHtmlWindow.SetPage(source)
does the trick. Linked images that are loaded from the web are also
no problem (very slow though .. known problem???), but some pages
need to load local images that are also stored in the database.
A work around would be to store the images in a temp diretory and use
OnOpeningURL to redirect to this dir.
What I would like to know if there is a cleaner or 'better' way to get
these images loaded on demand.

Yep, the pages themseleves too.
Create a wxFileSystemHandler that knows how to retrieve files from your database, and then refer to the pages and images with the new protocol specifier. For example: mydb://thefile.html. If all your links and image references are relative then I think you only need to specify the protocol for the first page when you open it with LoadPage.
