Rest of the things you need to do in theme files...

e.g.

`

setOption('albums_per_page', 4, false);

setOption('images_per_page', 4, false);

setOption('image_size', 150, false);

setOption('image_quality', 65, false);

setOption('thumb_quality', 70, false);

`

... blah.. blah..

Mobile site modification in previous version (1.0.8) of zenphoto was damn easy.

This new database driven options, (static-html-cache) plug-ins driven Zen-Photo wasted my more hours to recode mobile hacks.

well, that is one reason we recommend not changing core files.

The iPhone theme recently developed by a user seems to be the more elegant way actually.
