>>I got 17000 files. How long will it take?
It Depends On, Your Internet Connection Speed. The Plug-In Really Does Not Search For Images, It Creates A URL To A Image On The Fly, And Then Attempts To Download the Image If It Is Found.
This Is A Bit faster Than Doing A Search, And then Find The Results Of The Search, And Then Download And Store The Image.
Bit This Would Be Best For A Overnight Batch With That Many Files.
You Can Also Setup the program to search your local cover art folder first and that does speed up things a bit more so if there are more than one media file from the same album.
>> Where are the images stored?
It Depends On Your MC Settings
>> Does it replace images already found by Media Jukebox?
It Can If You Want, If You Don't Want It To, 1. Don't Put Them In Playing Now, And Or Do Not Turn On That Option.
>> Is there a way of batching by album instead of file by file?
No
>> Will it automatically download and apply the image if I select batch?
Yes
