I’ve installed attachment\_fu and when I try and upload a file, I get  
this validation error:

There were problems with the following fields:

Size is not included in the list

I’ve changed the model to say: :max\_size =\> 2.megabytes, but I still get  
the message. My test file is 721 kb. To keep thing simple, I’m testing  
with an image file.

I’m will be using attachment\_fu to upload documents, so I don’t need  
thumbnails and resizing, correct?
