That is unfortunate. It shouldn't matter, but are you using your own images for your videos or do you just have the generic image? Also, how many videos do you have in your directory?
One thing to check is to see if PIL is actually working. Browse to:
http://192.168.1.2:8001/media?name=images/folder_square.jpg&key=client
and you should see the JPEG of the folder image and if you check the properties the dimensions should be 533x533.
Now add a resolution to the end:
http://192.168.1.2:8001/media?name=images/folder_square.jpg&key=client&res=300,300
and the image should be scaled to 300x300.
Of course, replace 192.168.1.2 with the IP of your NAS.
