Pictures and stuff
Hey again,  
  
I started to develop my own plug-in on 0.7.9 based on one of the originals. I replaced the 'icon-default.png' image and it was updated in the ui accordingly. However now that I try to replace the file with another one, the old won't budge. Is is cached somewhere or what am I missing?

Yes, Plex caches all image data you send back from plug-ins. They’re stored in “~/Library/Application Support/Plex/userdata/Thumbnails”. Unfortunately there’s not really an easy way of telling which is which.  
  
  
  
Your best option would be to rename the “~/Library/Application Support/Plex” folder to something else while you’re developing - Plex will create a new one which you can work with, and you can delete the thumbnails folder whenever you need them to refresh. When you’re done, rename the old folder back to its’ original name. That way you won’t lose any thumbnails and fanart associated with your video files.

That would have been nice to know 🙂 But I did find that QuickLook works on the .tbn files.

You can determine the image file by looking at ~/Library/Logs/Plex.log when in debug mode. When the image gets loaded something like this is logged:

```auto

13:59:52 T:2687518496 M:290902016 DEBUG: Load /Users/username/Library/Application Support/Plex/userdata/Thumbnails/Programs/xxxxxxxx.tbn: 14.9ms

```

  
  
Then just delete that xxxxxxxx.tbn file from ~/Library/Application Support/Plex/userdata/Thumbnails as Jam already pointed out.
