imwrite(im,'new.png')

Considering that there's missing code and open scopes, we're left to guess whether anything is inside of a loop or not. Either way, it should be obvious that
imwrite(im,'new.png')
only writes an array to one file -- the same file every time. You're the only one who knows where this is in your code, so you'll have to figure out whether this is even being called more than once.
There are many examples of processing sequences of files
