Thumbnails for Image Files on Desktop won't load I have a dozen or so image files on my iMac's desktop.  Most of the time, after booting up my computer, it displays a thumbnail of each image (as it should).  But sometimes, the thumbnails won't show up (see screenshot below).



It appears to happen randomly.  I estimate that it happens about 20% of the time.

Why is this, and how can I prevent it from happening?  I am running OS X 10.9.4.  Thanks.
Based on your log, I suggest trashing the Finder property list, then rebooting.


Open Terminal
Enter the following command rm ~/Library/Preferences/com.apple.finder.plist
Restart
If the issue persists, I suggest following these instructions. to completely reset the service.
