title: file input - prevent selection of certain types of files and size
body: <p>Is there a way to prevent the user from selecting a file that is not a specified file type when they browser for the file on their computer?  For example, when a user browseses to upload an image file I would for them to only see images (jpg, png, ect.) that are less than 20mb.  Is this something that can be accomplished with asp.net mvc and jquery or do I need to use flash or a java applet?</p>
