To use a Theme they must be located within the Web app's App_Themes folder.
To create a theme you must create a sub folder to the App_Themes. The name of the folder must have the same name as the .skin file:
App_Themes
MyTheme
MyTheme.skin
To specify the theme you want to use, you use the name of the theme folder:
Page.Theme = MyTheme.skin
If the user already has a .skin file and you want them to upload the skin to the server, you can use the new UpLoad control.
