    Hi a few questions regarding File Upload elements:

    Question 1: No URL

    Looking at your getValueHTML() function for File Upload elements I have a question.

    Under what circumstance? would a file upload element have no URL?

    Question 2: File size

    File size attribute is that in bytes? So dividing value by 1024 will give k?

    Question 3: File type

    Is that MIME type? And how is that determined at time of upload? By extension?

    Question 4: Security

    If a file type is not in in the included list. Can a user rename file and bypass the check?

    Is there a way to protect the files once uploaded? Ie must be logged in to access? Any suggestions?

    Thanks again

    2,3. Awesome, the link helps heaps

    4. Ok, thought so

    5. Was aware of this but didn’t know how it would affect the plugin when saving files. Is it excused from security check?
