Just to consider: From a post in this forum I learned about using Hype animations placed as interaktive elements in HTML-wysiwyg-editors for building webpages.
One of these mentioned was the Sparkle App which I subsequently used in this project:
Sparkle is quite similar in use compared to other Mac programmes like Pages and Keynote and easy in creating very cool stuff very soon – build on your own imagination and layout ideas and not just picking pre build WP-themes to end up fighting with plugins and stylesheets to adjust the visual appearance. Thus you prevent the dull WP-theme terroir syndrome
The output can be either traditional multiple subpages er single page scroll designs with effects and appears both fast and consistent across platforms.
Also the placements of folders/subfolders is optional by own choice. Imported images are included in documents, optimized and processed just like in Hype.
