2 remarks:
- i am not aware that Gem can load png images on w32 at all (but might 
happily be mistaken :-))

- the reason why the files are "locked" is a weird bug in Pd (or my way 
to compile any external for Pd) that does not allow an external to 
properly close a file-handle created with open_via_path() (this has 
recently been discussed on the Pd-list (search for something like 
file-handle leaks), but i just noticed that i there is no proper 
bug-report on neither pd-gem nor pure-data...
