bug in util.php ?

[terrorhawk]

I was cleaning up my photo album by removing the original picture with the build in util..

and what did i see?
the util make change the images to normal_ as main picture (wich is good sow that the original pic cant be load again) but its also remove the normal_ picture from the server and leave the original pic on it. sow now i get a error that pic was not found

after restoring the normal_ pics from the backup i had made it worked again.. and after removing the original file it still worked fine..

sow is this a bug in util.php or is it somthing that i did wrong ?
