Cover Loading/Updates

hello, i recently downloaded a bunch of covers for my collection but the old ones appear to be cached in orangecd. is there a way to purge them from orangecd even though they do not exist in the folders anymore?

i also renamed all the cover files in my mp3 folders to folder.jpg. windows appears to like it to show the image on the folder itself. is it possible for orangecd to look for this file name as a default everytime you start orangecd and update itself?

thanks for the help, ive been very happy with this program so far.
