Your post is pretty hard to read. Please read writeup formatting tips.

Anyway, here's a reasonable start: 

# .. get data from blob into $blob_field.
print "Content-type: application/octet-stream\n"; # or use the right c
+ontent-type for the field if you know it
print "Content-disposition: attachment; filename=somefile.ext\n\n";
binmode STDOUT;
print $blob_field;

I have no idea what LWP has to do with any of this, though.

update: ah it appears you want a "file-download field" in your form. There is no such thing as such in HTML. My code above will work fine if you link to it though - it will (or rather, should) cause the browser to open a "save as..." file selector and save the content to that file. You can only send one file per request this way, so your best bet is to create a list of links for each blob field. In other words, the script above should be called as a CGI for each field.
