Forum:Image upload problems

I already submitted a couple Special:Contact reports, but I want to know if my problem is more widespread or not.

On WoWWiki, I'm getting this problem where when I try to re-upload an image that is just a cropped version of the previous image, it pretends to upload, but just shows the old image resized to fit in the new image dimensions. The new image is no where to be found even with multiple efforts to purge, etc.

I'm also seeing a problem where I get a bogus duplicate image warning when uploading and if I ignore it, the upload either fails or shows some previously uploaded image as uploaded.

Anyone else having similar problems? -- Fandyllic (talk &middot; contr) 21 May 2011 2:59 PM Pacific


 * Yes, same issue. From what I found it is a re-occuring issue. 90.216.25.75 22:43, May 21, 2011 (UTC)


 * Isn't it just cache? Sometimes the new version of an image is immediately visible. Sometimes it takes a few hours. This isn't just a recent thing as far as I know. Sometimes if you scale down wherever the image is used by just 1px, it will force the newest version to show without having to wait. -- Deltaneos (talk) 22:45, May 21, 2011 (UTC)

 * I don't think it is just a cache problem. I've been uploading lots of images and only recently have these strange problems started occurring. Also, I've never had it take more than a few minutes to show the new version and never had it give a duplicate warning and show me a completely different image from what I'm trying to upload.
 * I do wonder if it has to do with the sizes of the images though. Until recently, I've been uploading smaller images (<50K) and my recent ones have been a few hundred Kb or more. -- Fandyllic (talk &middot; contr) 21 May 2011 3:49 PM Pacific


 * Yes, it's a intermitent recurrent problem since at least 2 years ago. Images have some sort of timestamp number inside their URLs, so every time you upload a new version, they get a different URL. That in theory make the caching process more robust, since Wikia can tell the servers to cache that URL "forever". The problem comes when the system is broken, you upload a new version of the image, that gets a new URL but the file servers sends the old image. Then it's a big problem since the cache servers save the old image with the new url and no matter how many times you reload the page or use different browsers or computers, you got stuck with the old version of the image. I also found that even reuploading the same image even two times in different days (to see if it's a matter of servers being slow at syncing) the problem is still there.
 * It seems a problem that Wikia hasn't reach the solution yet. With Special:Contact Staff could refresh the server cache to get the new one displayed. At least some months ago, since the last time I tried Sarah Manley didn't seem to get the point that Wikia has several file servers &mdash;at least one in the US and one in Europe&mdash; and I have the bad luck that she was seeing the updated one (because she is hitting the US servers) and I the outdated one (because I'm hitting the Europe one), so she kept saying it was my (cache) problem while I trying to explain her about Wikia's server infrastructure with no luck. I hope you have better luck than me :) --Ciencia Al Poder (talk) -WikiDex 12:36, May 22, 2011 (UTC)


 * I'm a big fan of cropping images, so I have seen this problem several times, and have had 2 staff members respond to my reports of the problem.
 * There is apparently nothing that staff can do to resolve the problem, and it will simply fix itself in time. But it will not automatically update the image.
 * The only thing that has worked for me is to wait 6+ hours, then try uploading the image again (reverting between versions also works).
 * The good news is that I have been told that wikia is installing a new file server this week which should hopefully resolve the problem for good. -User452 13:05, May 22, 2011 (UTC)
 * Just for reference, I just experienced the problem again, and it took between 2 and 4 hours for the problem to fix itself, without any staff help. As I mentioned, simply refreshing does not fix it, you must either reupload or revert the image to clear the cache -User452 19:50, May 22, 2011 (UTC)
