It sounds like you are looking for "security" -
ie, password-controlled access. Or, a web application like
coppermine (google for details...)

This would only make sense in the context of a web
application that is fetching the images dynamically (ie,
mapping the dynamic URLs to arbitrary file locations). If
you have a link, post it and I'll have a look...

Yes - that's a PHP application that is handling the request
and reading the files off the disk. This bypasses apache so
can't be emulated by apache config directives.

I think you are confusing server-sided web applications,
like PHP, with apache. Apache is just a web server; it gets
files off disks and sends them down the wire. It can also
pass requests to other applications on the server (handlers,
like PHP) and they can get data for it, but they are not
bound by or controlled  by the apache config.

You can't do what you want to do with apache alone.
