You'll see that for some reason, my two new albums are not showing thumbnails. If you go into the Album, you'll also see the pictures are not showing up either. They are just .jpg photo's, i've tried renaming them as well, no luck. They just don't show up!

Any idea?

To add to this, they are 3 different type of camera/photos. I tried creating new albums, I even reinstalled zenphoto from scratch. Is there something my webserver is missing, or a setting I need to turn on?

I've also tried resizing the images, no luck.

Well, either your images are too big for your server (see the troubleshooting) or they are corrupt. It might be the latter as they appear blank when I tried to open them directly although I could see 1.8mb loaded.

I can open them on my PC, but once they get to the web, they seem to crap out. I've tried resizing them to something like 800x600, with no luck. Some turn out garbled in previews, until you click into it and get to the direct URL of the image.

You should check your CGI logs as there are probably errors there. The images are not rendering from the i.php process so they are not being cached.

Another question--have you modified the theme? The full image link seems not to be "standard". But when I click on it I see a really garbled image.

Wow, I had to tone the images way down to have them work. The image resolution was the problem.
