I host openerp on a aws server to try. When I upload images to products/customer/employee, only .png files are accepted. When I tried to upload a jpg file, errors as follow appeared.

Did I miss out setting the apps to accept jpg? I even go thru python lib and trace back to check necessary files, JpegImagePlugin.py are in the system.

I had tried several methods still cannot get the problem solved.
