Fixed size for all images and two rows (or more) menu

For PDA template.
Is it possibile to set a default size for all images?
How to put menu items on two or more rows? because there are too much items so I don't see all but just the first 5/6
It works great, but I need just those options.
It's MobileJoomla 0.9.8 under J! 1.5.22

What do you mean by "default size for all images"? If you mean default maximum image size, you can make a plugin that set this values (look at Mobile-Simple plugin as an example). If you mean that all the images should have the same fixed size, then how images with source sizes 10x100 and 100x10 will look after rescaling?

Yes, I mean default maximum image size. I will look at the plugin.
Thanks
