downloading multiple blobs as one file

I made a script for a friend which allowed the user to upload an image
file to a server which was then stored as a blob. However, I have not
come up with a good way to download the images other than downloading
them individually. Ideally, I would like to download them all as a zip
file or something like that. However, I don't know how to add blobs to
a zip file without using some sort of temp file to hold the blob. Is
there a good way to do this without having the physical files located
someplace on the server?

PHP's zip file functions are read-only as far as I know:
<http://www.php.net/zip>
So you can only use those to read zip files -- not make them.

I think the simplest way (if not the only way) is to save each of your
images to temporary place on the harddrive (i.e. /tmp/images) then run
the appropriate command using exec(). You can then present the
resulting zip file to the browser.
