The http://www.paris1914.com/ site has the worst user experience I've seen in quite a while. Somebody went to a lot of work to make the site have all those bells and whistles, and they totally blew it. It's just ridiculous! I move the mouse over a picture and the picture flips around to show me some info about it. OK, but what happened to the picture? I wanted to see the picture. So I try to click, and that only works half the time. You have to catch it quick before it flips around to display the title card. Good luck with that. Then if the click registers, it does this weird two-way-but-not-both-at-once animation and finally shows me the picture. Then I can close that, lose my place, and pick some other picture to look at more or less randomly.

This is NOT the way to make a photo gallery.

By contrast, the "blogspam" page has all the pictures in a simple page that I can scroll up and down. Nothing fancy, nothing I can't figure out, and no way to lose my place.

I was showing these pictures to a friend and it would have taken a good half hour to poke our way through the paris1914 site. But thanks to the blogspam page, we were able to enjoy all the photos in the time we had, without having to fumble through some kind of misguided navigation.

Again, I don't disagree with your point about posting original sources, but in this specific case, the blogspam was very beneficial to me at least.

Edit: So I thought to myself, maybe I should give this thing another chance. Once you get one of the photos open, maybe you can just skip from photo to photo right there? Indeed you can, and it even has a keyboard interface: the left and right arrows work just as expected.

But what's all this scrolling? It doesn't just change photos like a slide show, it does an enormous sideways scroll of the whole thing. It's very disorienting visually and not at all fun.
