Nope, not a widely supported anyway, I seem to remember some browser
specific options, but they don't play nice together. If this is a must,
look into a flash (or possibly java) uploader, which can be more
controlled (varying from just type to selecting while directories/mulitple
files at once). Be sure to provide a clean HTML fallback.

accept = content-type-list [CI]
This attribute specifies a comma-separated list of content types
that a server processing this form will handle correctly. User agents
may use this information to filter out non-conforming files when
prompting a user to select files to be sent to the server (cf. the
INPUT element when type="file"). http://www.w3.org/TR/html4/interact/...ml#adef-accept
So:
<input type="file" accept="image/jpg, image/gif">
Not tested.

The operative word is "may" and *none* of the browsers I have FF,

The only way check at the receiving server side script. You can use the
option of additionally prescreening the selection with JavaScript.

This seems to rely on MIME types (amongst other things), so in principle
could I send a file abc which is encoded as a gif or jpeg and have it
accepted? If the string above worked and no others, what of image/jpeg or
image/jpe - are these also encoded by the same codex? To the strict
letter of the OP, perhaps all you need to do is check the last three
letters of the filename, but that may run into issues with things like
def.gif which is actually an executable..?

Hello,
I'm trying to put together a form with a very tight table formatting.
However, every time I put an text-type input field in, the browser
pads the area to the right of it with space. I've tried to eliminate
it several ways, but it won't go away.
It looks like it's forcing at least one space (line break?) in after
each field, and then there's some mystery padding on the right that
also refuses to go away. I've put up a demo of...

with a
<BUTTON><IMG SRC=...></BUTTON>
The problem is that <BUTTON> always provides a shadow/emboss effect.
Can I get rid of that? If the old <INPUT> button has been deprecated in
favor of <BUTTON>, have all it's button functions been duplicated?
Thanks for any help,

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
