Here’s a great K-base Article that will explane a lot of the basics.
This post may be of some help.
As that thread will sigguest NVU is a geat WYSIWYG (what you see is what you get) web editing program. It’s free for starters, and it’s easy to use. There’s an FTP program bundled into the program to ship the website from your comptuer up to your DH server. There’s also a WIKI article to help you get the FTP settings right for your account (or search the forum and you’ll find instructions here as well)
You might consider using a photoblog or some other gallery type for your family photos. There is a oneclick install of Wordpress aviable in the panel for you, which is very easy to set up. You can do a simple google search for Wordpress photoblog, and that shoudl find you some instructions for setting up wordpress to handle lots of photos in a nice manner. (I might add that the photoblog instructions may not be as easy to set up as the blog it self.)
I’m really not familair with any photo galler type applications, but if your interested I’m sure some other people from this forum can point you in the right direction.
Hope this helps.
