There are 2 ways of importing skins into UCCW.
1. Open UCCW form your app drawer. While on the skin creator screen, click your menu key and select import skin. Go to the folder where your skin is located and select it. That is it.
Your skin must be in a .uzip format in order for this to work.
You may get just a white square after importing it. Go to manage skins and you will see it there, or add a widget and select the newly imported skin.
2. You can also place the .uzip and .uccw skins on the ultimatecustomclockwidget folder in your sdcard. Then open the skin manager in the uccw app and your skins will appear there.
Make sure you place the skins in the ultimatecustomclockwidget folder, and NOT in the uccwoutput folder.
If you want to add weather images, add the themed weather folder to the weather folder inside the ultimatecustomclockwidget folder in your sdcard.
