Email unable to send - error resizing images

Really need the full exception, stack trace and everything.  I would probably recommend opening a support ticket on this one.

---> System.IO.IOException: The process cannot access the file 'F:\Inetpub\community\Web\filestorage\communityserver.components.imagefileviewer\communityserver\components\avatars\00\00\00\27\07\4U2RJMLGREWW.jpg-70x70x2.jpg' because it is being used by another process.

So this is really an issue where some windows other process, like virus scan or some other tool has got an exclusive lock on the file.  I would check to see if anything running could be doing that.
