Admin Forum:Purging an image and regenerating delay

I know that after uploading a new version of an image, we generally access the purging page to force the software to make a new thumbnail of it. But I don't know why, that the time for refreshing became too long these days: sometimes it even takes hours! It's a pain for me that I cannot visualize the layout with the correct image and have to spend a long time to continue editing. Am I the only one to feel it inconvenient?


 * Problems with proper displaying of new revisions of images have been an issue on Wikia for as long as I can remember. You're not the only editor for whom this is an inconvenience. The best way to deal with it is to report it through Special:Contact. — Sovq 07:21, May 12, 2012 (UTC)


 * @Sovq: Does purging the page actually create a new thumbnail? --


 * For me not. I mean, for every wiki sites I'm working on. Although I'm curious about what will be happening if I let the page without purging it.(?)


 * I ran a few tests and no, purging does not seem to re-create thumbnails.


 * I found out how to force the creation of a thumbnail, though. There's two steps: First you need the image ID. Let's say your image has the name XXX.png, then the request would look like this:


 * http://yourwiki.wikia.com/api.php?action=query&titles=File:XXX.png&prop=imageinfo


 * From the reply you can get the image's "pageid". With that you can request a thumbnail:


 * http://pecoes.wikia.com/api.php?action=imagecrop&imgId=YYYY&imgSize=600
 * (YYYY is the pageid)


 * But I can't think of a clever way to use that trick. This new thumbnail does not update the version you will see in the article. It is a completely separate revision - one that is not even listed on the File:XXX.png page. You can only request it by its full URL. --
