My drives have both pictures and music.
I am also using a portable USB drive and the same thing happens: picture (jpg) thumbnails are not showing up when viewing the drive as a plugin, no matter what view scheme I use. THe "thumbnail" is the default image when there is no thumbnail. The image also doesnt appear throught the AW image feature.
Also, my drive is not refreshing correctly. If I add pictures to the drive, while still using MC, the new pictures will NOT show up in the drive plugin even upon refreshing. However, the pictures WILL show up if I browse for the drive in "My Computer" within MC. I have to restart MC for the plugin portable attribute of the drive to show the changes. I hope this makes sense!
