The folder labeled content_type is invalid according to the application, but not

Question

I am new to Paperclip and it all worked pretty fast. I am trying to get the user to only load PNG or JPG, although although I load JPG and my content_type checks JPG, it still says that it is not valid.

I tried to remove the PNG content_type, but to no avail.

I tried using has_attached_file, but it seems to be ignoring: content_type and stuff. Because if I download JPG only with :content_type => "image/png"; It doesn’t give an error.

Any suggestions?

    validates_attachment :avatar, :styles => { 
                                    :medium => "300x300", 
                                    :thumb => "100x100" 
                                }, :content_type => { 
                                    :content_type => "image/jpg", 
                                    :content_type => "image/png"
                                },
                                :size => { :in => 0..1.megabytes }

Oh, and while I am; I want my thumb and environment to be fixed. So no scaling, like 100x80, but only 100x100 anyway. How can i do this?

I compared the log to the server and noticed different content headers. It should be "image / jpeg"
