Hi, been having problems with my image uploads with Safari and firefox,  
i get it working with one, and it brakes in the other, and vice versa.  
This problem manifests itself during an edit, if no image is selected on  
the form.

I have the following code in my model:

def main\_picture=(picture\_field)  
STDERR.puts picture\_field  
if picture\_field != “”  
File.open(“public/images/#{sanitize\_filename(picture\_field.original\_filename)}”,  
“w”) { |f| f.write(picture\_field.read) }  
end  
end

if i excersise exactly the same code in both browsers, i get different  
output for the line STDERR.puts picture\_field

firefox gives me:

#StringIO:0x256860c

safari gives me a blank line. It also gives me the error:

undefined method `original\_filename’ for “”:String

It seems that firefox correctly returns a picture object, but safari  
returns a blank string.

Any ideas?
