New image viewer supports mobile devices

The Roman de la Rose digital library has added a custom touch-enabled image viewer to support browsers without Flash. Mobile devices which lack Flash support, such as the iPad, iPhone, and some Android phones, can now fully use the site.


In order to use the new image viewer,  turn off Flash support in the left sidebar. Clicking on the “Flash” check box will switch between the new image viewer and the Flash image viewer. By default iPhones and iPads will have Flash support turned off.


The image viewer has been tested on most modern browsers and a number of mobile devices, but undoubtedly problems remain. Please send bug reports and feedback to contactus@romandelarose.org. Bug reports should include your browser name and version.


The new image viewer has three modes, thumbnail browser, page turner, and single image viewer.

General features:

  •  Touch and gesture support on mobile devices (iPhone/iPad, Android phones/tablets)
  •  Dynamically responds to browser resizing and orientation changes

Thumbnail browser

  • Only loads thumbnails being viewed
  • Click/tap to go to page turner

Page turner

  •  Due to layout issues, the annotation display has become a draggable dialog
