Uploading in file column failed

Hi guys,

I’m using file column in uploading my images in a server. I had no
trouble in installation and even in implementation of it. However, I
usually encounter failure in uploading a picture despite of the fact
that I actually upload a picture.

I tailed out my log file and I got this parameters:

Parameters: {“content_title”=>“xxx”, “w”=>"",
“we_cms_image”=>{“image_temp”=>"", “image”=>#StringIO:0xb7236934},
“action”=>“save_subcontents”, “choice”=>“i”, “controller”=>“cms_admin”,
“h”=>""}

Please help!

Thanks,

Jeremy
