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

Tue Jan 8 12:26:26 UTC 2008

Thanks Itay! This worked!
But same as you I'm curious about the logic behind it. As there is a limit
of 20M for some reason. 2500 x 1600 pixels generates far less than
20MegaBytes I would say. And then it's only in case of thumbnail view...

I'm open for suggestions :)

Regards,
Grietinus
