Removing the OzioGallery footer

When Ozio Gallery is used within Joomla pages, the component displays a footer
OzioGallery2 by Joomla.it

If you search the source, you will not find the text as it is encoded (with base 64) within
“\administrator\components\com_oziogallery2\css\ozio.css”

1. Use http://ostermiller.org/calc/encode.html to decode the encoding in the css file.
2. Then remove the text that is not wanted and encode again.
3. Then paste it back to the css file, replacing the original text.

Note: For OzioGallery3, the folder structure seems to have changed. The ozio.css file for OzioGallery3 is located within the folder "administrator\components\com_oziogallery3\assets\css".
