Is there a theme where the album page has each images details included? Seems in the ones I've seen, you have to click into the image to see that.

What do you mean by details? Some of the themes have flash players that show an image on the album page that you either run as a slide show or brows sequentially.

What would be useful for us would be to have the image title, description, and tags right on the album page. Also good would be the images size in terms of height, width, and filesize.

We're using zenphoto as an internal tool/repository to track images of our products (different angles, different packaging, seasonal packaging, thumbnail vs catalog image vs hi-res original, etc).

Then put the functions to that within the next_image() loop on album.php. Please take the time to read our theming tutorial to get familiar with how zenphoto themes work and also at our functions guide.
