Hello
as active the viewer in owncloud 10.
example: view pdf, txt, image online without downloading
to solve online visualizations, just access owncloud as admin and go in the market option, you have the following options: pdf viewer, notpad, gallery, etc …

Does this work for the Android app as well? I am wanting to view images etc without always downloading. Downloading seems to defeat the purpose of centralized storage. 
Thanks!
