Hello and sorry for my limited English.
I've written a little script that I use to automatically retrieve the Wikimedia Commons "picture of the day" and save a local copy on my server in different sizes (width=200px, width=400px and width=1024px).
I call the file with this URL: $distantfile = "http://commons.wikimedia.org/w/thumb.php?f=".$filename."&w=400" (replacing "400" with whatever I want: 200, 400 or 1024. (Thumb.php is a script used to resize images)
My little script has been working fine for two years. However I've noticed several issues since ~ day 20th of October. It looks like thumb.php on Commons is now repeatedly generating errors with some sizes.
Example with the “picture of the day” of today (try it yourself in your web browser):
