How would that work? How would the browser look at a file name and
decide whether that file is one of the specified types?

And how many browsers implement that property anyway?

The page at http://htmlhelp.com/reference/html40/forms/input.html
says: "Current browsers generally ignore the ACCEPT attribute." I
suspect that's true (but I don't know for sure).

I tried in on IE 8.0 and it is ignored. From the File
Selection DialogBox that is displayed There are three
filetypes that can be selected:
(a) All Files
(b) Image Files (including PNG)
(c) HTML files

I have tentatively rejected the Java way because it seems to
be less secure for the client.
