Hello everyone,
my xwiki seems to do strange things to embedded pictures. No matter
how big the resolution is they all are displayed blurry (as if they
were scaled down and then up again).
Can anyone explain that behavior? Does anyone know what to do against it?
Thank you for your help,
Stephanie

Stéphanie,
my XWiki never did image refactoring.
However, my UMTS stick internet provider (1&1, through vodafone, could be the same
with SFR) does it always by default: it applies fairly strong jpeg compression to any
image request. That gives a pretty dusty web effect which is pretty horrible and can only
gotten rid of by actually emptying cache.
hope it helps.

Does this happen only with attached images or even with external images?
If you have this problem only with attached images, then how do you
embed them? If you're using wiki syntax and you specify the size like this:
[[image:Space.Page@image.png||width="300"]]
then the image is resized on the server side to optimize the amount of
data transferred to the client. You can disable this from the
xwiki.properties file (rendering.imageDimensionsIncludedInImageURL) or
increase the level of quality from xwiki.cfg file
(xwiki.plugin.image.defaultQuality, 0.5 by default, 1 meaning best quality).
Hope this helps,
Marius
