[thelist] File upload filter (via Javascript) before submitting a form?

Is there any way to test (and filter) the file input before submitting the
form? I want to allow the user to upload image files within certain size and
formats e.g. 200k jpeg or gif. However, the JavaScript objects for the file
input seems to be very limited (probably for security reasons). I know how
to get the filename and test if it has correct extension but I want to get
MIME type and size to - is it possible?
