hi any one help me to get the icon mode working on a 5100 this is what the manual says but it dose not make much sence to me

Support browsing by icon mode
Make a empty file named as "icon.tvix" on the folder that you want to browse by icon.
The file name for the file used for the icon files is case sensitive, it must be the exact same name as the
media file except that the extension must be jpg or png(if you want to use transparency, set the
transparency color as 0xC8C8C8.)
To show the folder as icon, please put "folder.jpg" or "folder.png" on the folder.
The maximum icon size is 720 * 480, and the best size is 100 * 136.
