File Input Accepted File Types

[The Little Guy]

I have never tried this before, but is it possible to tell a browser what types of files are valid in a "file" input?

 

I would like to tell the open dialog box that I only want to allow jpg/jpeg, gif, and png

 

is this possible?

 

if not with HTML, how about JavaScript?

HTML:  Yes, but no.

(there is an attribute, but it is not supported)

 

Javascript: ~unsure

You could probably check the extension on the submit attempt.

 

But since all this can be bypassed, you will ultimately have to ensure the type fits your wants on the server side.  Remember, I could make any form I wanted on my server and target your server for the action attribute; as long as I match your $_POST[] array names, your server (by default) would try to accept it.

I know, I just want it for ease of use.
