No Purging On Newer Version of Images

NOTE: Parallel discussion in progress at Commons:Village Pump#Problem with new version of image.

I uploaded newer version of the Introspective cover art. While the image page is already updated, the article shows the prior version of the cover art. How long can I wait? --George Ho (talk) 03:06, 11 December 2012 (UTC)

Have you tried clearing your page cache? It could well be golding the 'old' version of the page. NtheP (talk) 15:42, 11 December 2012 (UTC)

I did delete "Temporary Internet Files" on Internet Explorer 9; old versions of images still appear. ...Well, I'm now seeing newer version of Showdown (Cheers)'s infobox image. However, Baby, Come to Me (Patti Austin and James Ingram song) should have the Japan single; I'm now seeing a French single. --George Ho (talk) 16:12, 11 December 2012 (UTC)

It appears the old thumbnail caching bug from mid-2011 has reappeared. I remember first seeing it around 23 May 2011 and the problem persisted to a greater or lesser degree through the summer of 2011. Around that time many users also reported very slow Wikipedia performance, even those on high-speed connections. I haven't seen much in the way of Wikipedia slowness (yet), but an image that I was trying to update yesterday failed to update the thumbnail cache, even after clearing my browser cache and purging the pages at Wikimedia Commons and on the English Wikipedia where the image is used. I tried a test edit by changing the thumbnail size by just one pixel, and the revised image appeared as it should have, but not if the image continues to use the same old thumbnail size. In 2011 the thumbnails would eventually get updated, but it could take 24-72 hours. I seem to recall this was assigned a bug tracking number, but after searching the Village Pump archives here and at Wikimedia Commons, I haven't been able to find the thread where that was mentioned. It's possible that the root cause was never properly identified and corrected, or someone may have re-introduced the bug with a software change that picked up a chunk of old source code from around mid-May 2011 or thereabouts. — QuicksilverT @ 05:46, 12 December 2012 (UTC)

Even just changing the filename seems to fix the image; look at File:KDEN-TV Logo.png, which I changed from File:Logo-denver.png, while the unchanged File:KFWD T52.png is still waiting to get my change in. Nate • 06:09, 12 December 2012 (UTC)

bug 28613http://bugzilla./show_bug.cgi?id=28613, I think. --Maggie Dennis (WMF) (talk) 19:41, 12 December 2012 (UTC)

That's it! Thanks for digging up the reference. — QuicksilverT @ 03:44, 14 December 2012 (UTC)

On File:Obama and Duke Duchess of Cambridge.jpg I get the following message on the 800px thumbnail no matter how much things are purged or refreshed, but can get other non-800px sizes: Error generating thumbnail
Error creating thumbnail: Image was not scaled, is the requested width bigger than the source? -- AnonMoos (talk) 13:45, 14 December 2012 (UTC)

Right now, the files are not loading properly (or is loading slowly). Are tech guys debugging the problem? --George Ho (talk) 23:13, 17 December 2012 (UTC)

Or maybe it's short-term loading problem. Now I'm confused. --George Ho (talk) 23:15, 17 December 2012 (UTC)

Loading issues resolved? I see that loading is all right. Now then, anything uploaded this week has no issues. Look at "Smokin' in the Boys' Room"; loading is stable. --George Ho (talk) 04:38, 18 December 2012 (UTC)
