Hi Jonathan,

How about something like this, uses a bit of scripting instead of all that css stuff:

#!/usr/bin/perl -w
use strict;
use warnings;

use CGI;
use CGI::Carp qw(fatalsToBrowser); #errors will show in the browser

my $co=new CGI;

print $co->header,
$co->start_html(
 -title=>'fileupload.cgi',
 -BGCOLOR=>'#FFFFFF',
 ),

$co->start_form(
 -method=>'POST',
 -name=>"myForm",
 -action=> "http://localhost/cgi-bin/fileupload2.cgi",
),

$co-> filefield( -name => 'browse',
                 -style => 'display:none'
                  ),
$co-> textfield( -name => 'file',
                  ),

"    ",
"<a href=\"#\" onClick=\"document.forms[0].browse.click();document.for
+ms[0].file.value=document.forms[0].browse.value;return false;\">",
"<img name=\"browse\" src=\"http://localhost/html/browse.bmp\" alt=\"b
+rowse\" border=\"0\"></a>",
$co->p,
$co->image_button( -name => 'submit',
                    -src => 'http://localhost/html/add.bmp',
                    -value => "Submit",
                    -onclick => "document.forms[0].browse.disabled=tru
+e;document.forms[0].submit()",
),

$co->end_form(),
$co->end_html;

exit 0;

I've tried this myself and it does appear to work.
Enjoy,
