Image overwrites form #attributes

I noticed this issue while trying to add a class to my custom node type form.
On 2 occasions this module will overwrite the already set #attributes.
This happens in image.module and immage_attach.module.
A fix is simple: just replace $form['#attributes'] = array("enctype" => "multipart/form-data"); with $form['#attributes'] = array("enctype" => "multipart/form-data");
