[TYPO3] NO to multipled images

[T.Joga]

If you dont like that typo multiples images like image-01.jpg, 
image-02.jpg ..etc. you can do this:
\typo3\t3lib\class.t3lib_basicfilefunc.php
around line 280

function getUniqueName($theFile, $theDest, $dontCheckForUnique=0)	
change to:
function getUniqueName($theFile, $theDest, $dontCheckForUnique=1)	

this prevents typo to unique picture names to "-01", "02"..

\typo3\t3lib\class.t3lib_tcemain.php
around line 1660 or 1825

t3lib_div::upload_copy_move($theFile,$theDestFile);
change to:
if(!file_exists($theDestFile)){ 
t3lib_div::upload_copy_move($theFile,$theDestFile);	};

When you copy default content elements in multilanguage site, files are 
wiped to 0bytes if you dont make this change.

I dont give any guarantee for this dirty hack. I am no expert with typo, 
so there could be a really simple way to situations like this?
