How to validate corrupt image file while uploading using Rails

• if the corrupted jpg or png file (or change the extension of any other type of file to jpg)

  the system will have to show error during upload

解决方案

You can check the MIME type to make sure that it's not file with a changed extension by using the mime-types library.

type = MIME::Types.type_for(your_file.original_filename).first

I'm not sure how that would work with corrupted/broken files though. Make sure to look into Paperclip for uploading files, as it's ridiculously easy to set up and use.
