Forum:Thumbnails not generated correctly

Hello, I am from http://hkrail.wikia.com

I have contacted the staff yesterday but I have not had reply currently.

Some thumbnails of images cannot be generated correctly. For example,

Thumbnails of animated gif images cannot be generated also, Imagemagick may not be installed.

How can the problem be solved? Thumbnails cannot be embeded on articles correctly.

 * All thumbnail are showing ok for me on
 * http://hkrail.wikia.com/wiki/Gallery:%E7%9F%B3%E9%96%80%E7%AB%99
 * where the first two pictures are used.
 * For the GIF, are you sure wikis are supposed to support animated one ? — TulipVorlax 10:05, 19 July 2009 (UTC)

Look back these two image pages:, the 800px thumbnails are not showing correctly. However, all 120px thumbnails can show properly. Why?

And another thing is: When the 800px thumbnail can be generated, all other thumbnails (e.g. 280px) can be generated also. How strange.

 * Many people comes each month on the Central forum asking why this or that don't update.
 * I've been one of them to.
 * But after (more than?) two years on Wikia now, i know that things will get updated, one day.
 * The number of wikis on Wikia is increasing each day. The number of users too.
 * The number of servers dont increase each day.
 * This cause many different kind of caching and updating problems.
 * Often when uplaoding new version of a file, for many days we still see the old image stretch both on page it is used and on it's own page.
 * New users that dont know things will update if they wait some days will uplaod the image again, and again, and again...
 * And that makes things even badder on the servers.


 * If thoses images pages have not updated in about one week, use special:contact to send them a link to it. — TulipVorlax 23:08, 19 July 2009 (UTC)

This image is uploaded on the 1st of July, 19 days later (today), there are still no thumbnails.

One of the question is, why the 120px thumbnail can be generated but others cannot?

For others, if one of other thumbnails (e.g. 800px) is generated, others with different sizes(e.g. 260px) can be generated instantly also.
