If you ever pay attention to the default Windows 7 Theme build in, those themes will have a perfect image screen resolution no matter what size of the screen your device is on. It looks perfect on the Netbook, if you switch to a 27' inch monitor it too looks fantastic.
The default theme is located in
and if you ever bother to look into the file, those themes is calling a dll to somehow adjust those images according to your native screen size. (lets use Landscapes as an example)
The image of the Landscapes theme is located above, but you will realize the image are perfect match to your current screen resolution.
That's probably why of course all the default themes looks good across all type of devices.
Now my question is how can I create a Windows 7 Theme that does those dynamic screen resolutions adjustments depending on the current resolution of the computer into just one Windows 7 Theme pack. (I know how to create a Windows 7 Theme, please don't tell me how I can do that)
