Fre:ac is adding additional album art during conversion ?

[EM1138]

I converted many flac files to wma and the wma files have 2 additional album art images. One is 200x200 and the other is 75x75. Mp3tag shows only one image attached to the flac files but 3 to the wma files. How do I stop this from happening?

I think there was hidden album art files from Windows Media Player in the folders that fre:ac was attaching to the flac file.
