Actually, you don't need to modify the upload code to prevent people
from uploading.
MediaWiki has had a pair of upload permissions since 1.6:
* upload - Allows for uploading new files
* reupload - Allows for overwriting files
* reupload-shared - Allows for uploading a new file even if a shared
file under the same name already exists (Obviously only useful when
using a Commons type system)
To allow uploading of files, but not overwriting of them you would use:
$wgGroupPermissions['user' ]['upload'] = true;
$wgGroupPermissions['user' ]['reupload'] = false;
$wgGroupPermissions['user' ]['reupload-shared'] = false;

Hi there,
is there a ready to use way to prevent file upload without an assign licence?
We do not want preload some "common" licence but offer a blank choice and force
an input (selection from the list).
Well, you can provide a license-dropbox like the one used at commons:

Can we avoid source changes?
What do you mean? Blocking the image file from editing or the file for
reuploading? Both should be possible (the later may require a small
change in upload code). But the original text will be always shown...
that's why wikis hava a history after all.
