copy whole cimy-header-image-rotator subdir into your plug-in directory and activate it
create /wp-content/Cimy_Header_Images directory and set write permission for the web server
UPDATE FROM A PREVIOUS VERSION:
always deactivate the plug-in and reactivate after the update
HOW TO USE IT:
first of all you need a directory where all images will be stored, the directory MUST HAVE this name: ‘Cimy_Header_Images’ and MUST BE placed under: “wp-content” dir
example: /wp-content/Cimy_Header_Images directory and give it 777 permissions if you are under Linux (or 770 and group to “www-data” if you are under Ubuntu Linux).
go to Settings -> Cimy Header Image Rotator
upload some images
change the swap rate as you wish
copy/paste the code you find in the same page to your favourite theme, where you want: inside header.php or sidebar.php etc.
