[Mediawiki-l] Is there a way to limit the size of images uploaded

I also encountered this problem.
However it does not seem to be related with the bytesize but more with the
imagesize. Whenever an image exceeds the size of approximately 1600 x 1600
pixels, the "Fatal Out of Memory" errors occur.
It is, as Norbert says, only when Thumbnails are involved...

Kind Regards,
