suggestion for custom flash cards manual input

I have a suggested improvement that will help the website and learners much better than the existing flashcard system.

1. For manual entry where users create their own custom flashcards - change website to allow uploading of .wav audio file if the word or sentence is not part of the course already. It is silly to have flashcards with no audio.

2. As above also allow uploading of .jpg or .gif files of certain sizes to complement the flash cards. 

This will greatly assist those who learn new words by use of flash cards or those who want to create a more elaborate set of their own not covered by the existing course.

Or just use a dictionary and make your own.  Not everything has to be on the internet.
