Thread:Project:Support desk/Why does MediaWiki try to create the same thumbnail multiple times?/reply (2)

Issue 49528 created.

I have now stripped down the situation needed to reproduce this weird behaviour:

This is the wiki text, which I am using:

Image.png has a size of 450x151 pixels and in the page it is given out in original size. So the image should not be thumbnailed at all - and especially not to 450x151, which is the original size.

The wiki is
 * without any extension
 * with the vector skin

The problem exists
 * no matter, if a user is logged in or not.
 * no matter, if I set $wgUseImageMagick = true; (so that ImageMagick is used for scaling) or $wgUseImageMagick = false; (so that GD is used)

The error does not happen, when the image should actually really be made smaller: Then the thumbnail actually is created and is used on later hits.
