on a couple of occasions i have recieved small programs that have arrived with the unfamiliar tag '.img' rather than '.sit' or '.exe' or what have you. the file is identified as a 'limewire' document and if i try to open it it simply opens the limewire window.

the file size seems correct to the program i would have expected and it was recieved 100%.

is the file toast or can it be revived with resedit or some such method.

any detailed response should be warned that i am a mac user.

thanks in advance for any thoughts on the issue.
