This is to be used with and widgets that have weather icons. After downloading and unzipping just cut and past the weather set folder to the themes weather set folder you want to use, whether it's in an iWidget or LockHTML, and rename it to what the currently used icon set is named. But you must rename the current one to something else in order to name the new set.
