I have a ZenPhoto 1.4.1.3 site, and am trying to see how it will appear on mobile devices. The W3C Mobile Validator reports "More than 10% white space" on my top site page where I have ZP embedded. If I look at the code on the page in in View Source, there is indeed a lot of white space coming from the ZP code.

I have the regular ZP index.php material on the page, showing a series of album thumbnails.

Does anyone know where I would go in the ZP code to try and remove some of the white space?

There have been some themes designed for mobile devices. a quick search found http://www.zenphoto.org/news/mobile-theme-filter. However that is listed as introduced with ZP 1.3.1 so may not still be compatible.

There is actually only one theme for iPhone that is explicit for mobile devices.

But specifially for that device I think and maybe not compatible.

While the standard themes are not optimized for mobiles (I am planning a rough basic theme using jQuerymobile once that left beta statuts btw.) they should work with smartphones that actually have a proper browser.
