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/mulitp=
le =

files at once). Be sure to provide a clean HTML fallback.

accept =3D 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=3D"file").

So:

<input type=3D"file" accept=3D"image/jpg, image/gif">

Not tested.

^^^^
The operative word is "may" and *none* of the browsers I have FF,
SeaMonkey, Opera, IE and old Netscape do.

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