Topic: Protect Gallery with password

I use simpleviewer together with the svmanager.
I want to protect my gallery with a password, so that eyeryone who
enters the URL to my gallery first has to type in a password.
I googled for quite a while and the first thing I found was
to protect my gallery with .htaccess. This worked perfectly but I noticed
that for some reason with .htaccess the Java uploader of the svmanger
quit working.

So, do you have any hints how I could get my upload working with .htaccess
or how I could protect my gallery?

Thanks a lot,

Oh, and sorry for my poor english ;)
