If you run "./texturecache.py jd addons tmz" you should see the artwork urls associated with the addon - check that these artwork items exist, and are accessible to XBMC (as long as they're in the .xbmc/addons folder, they should be accessible, but if you're doing something like path substitution then all bets are off!)

You can search for the cached TMZ artwork with "./texturecache.py s tmz" - this will list the database rows with matching urls (urls containing tmz - use the same urls from the above "jd" call if you want to be more precise). You can then delete individual rows and associated cached artwork files with "./texturecache.py d #" where # is the rowid (left-most column in the list).

After removing any cached artwork items you can then perform a normal cache pre-load with "./texturecache.py c addons tmz", that should pre-load any missing (ie. recently deleted) artwork items.

If you still have errors then enable debug log (wiki) in XBMC, ideally with curl debugging enabled, and upload it to pastebin after trying to preload the cache for this addon. A logfile from texturecache.py would also be useful (add @logfile=/tmp/tc.log when pre-loading the cache and upload tc.log to pastebin.com).
