Re: upload image with cgi

    What do you need to know? You example works uploading a file. You just need to write it to a file. So instead of doing a print to the browser (which would just show the data of the image not the actual image) just write it to a file.

    Just check to make sure it's an image and write it to a binmode'ed file handle.

    Untested Code: 

         my $filename = $cgi->param('uploaded_file');
     my $type = $cgi->uploadInfo($filename)->{'Content-Type'};

     #use the upload function
     if ($type eq 'image/jpeg') {
       open(IMAGE,">/image_dir/filename.jpg");
       my $fh = $cgi->upload('uploaded_file');
       binmode(IMAGE);
       while (<$fh>) {
           print IMAGE $_;
       }
       print '<img src="/image_dir/filename.jpg">';
     } else {
       print 'Not a JPEG<br>';
     }

    Try This. 
     #!/usr/bin/perl -w 
 use CGI; 
 $upload_dir = "/home/mywebsite/htdocs/upload"; 
 $query = new CGI; 
 $filename = $query->param("photo"); 
 $filename =~ s/.*[\/\\](.*)/$1/; 
 $upload_filehandle = $query->upload("photo"); 

 open UPLOADFILE, ">$upload_dir/$filename"; 
 binmode UPLOADFILE; 

 while ( <$upload_filehandle> ) 
 { 
   print UPLOADFILE; 
 } 

 close UPLOADFILE;
