Ok I tried Gallery and tried to like it but after I had a look at Flickr I decided that was the way to go. Don't get me wrong. Gallery is an excellent piece of software but it seemed so slow . I didn't really go through any of the code to see what the specifics were as I relied on Fantastico for the install, although I had to manually upgrade to the newer 2.2 version. And yes I did play with the performance options.
I think Gallery is excellent if you want to keep all your photos on your own webspace or if you are a professional and want to sell them. But for novice photogaphers like me who just want to show off photos from their latest excursions and share experiences then you can't beat Flickr. There is a lot in Gallery to make a fully functional gallery but maybe that's the problem. The installation was huge.
Before anyone says anything, I tried Google's Picassa. But after uploading a photo I found it has a restricted license in that your photos can be used by Google for their own purposes. It's wise after all to read license agreements, something I don't do these days. Also Picassa didn't seem as fully developed as Flickr.
So here is my Flickr photo gallery.
