In general Imager uses the _valid_image() method to check whether the image a method was called on has an actual image stored, as opposed to being an "empty" image. This is safe(ish)* for objects supplied as "$this", since it will always be an object, but write_multi() calls _valid_image() on non-invocant parameters, if these aren't objects of any sort, or aren't Imager objects then the program will crash with a Can't locate object method "_valid_image" via package "bad class name here" error. The following changes are needed: - _valid_image() should handle being called as a class method (and fail with a new error) - write_multi() should check the images provided are blessed objects and isa("Imager") before calling _valid_image() * it may have been incorrectly called as a class method
