Thread:Project talk:Support desk/Start with uploading Logo

I just installed mediaWiki, and I am new to it
 * MediaWiki 	1.15.5-2squeeze5
 * PHP 	5.3.3-7+squeeze16 (apache2handler)
 * MySQL 	5.1.66-0+squeeze1

I want to put a logo-image. The result is:

"The file you uploaded seems to be empty. This might be due to a typo in the file name. Please check whether you really want to upload this file." Anybody can help? ZJ (talk) 14:23, 24 July 2013 (UTC)
