I have attachment\_fu running for some photos and have 2 nagging problems  
I can’t seem to resolve.

1. I want to change the default file-mask attachment\_fu uses on all the  
files it generates (original and thumbs) and didn’t know if there was a  
way to do it without actually invoking file ops from the ruby code (e.g.  
a flag I can set somewhere)

2. When I set the processor to none and change the file-types allowed,  
then upload a file, it goes through then complains that it couldn’t find  
image\_science (which of course I dont want it too because I set the  
processor to none)

thoughts?

thanks
