I think we can all agree that horizontal scrolling is usually bad, and vertical scrolling is usually perfectly fine.

But what about when you're showing the large view of an image?

Here's how I usually handle it. Make sure that the width will fit in 800x600 browsers (usually 500px or so), and let the height stay proportional. It's worked great so far, since most images have been reasonably square.

But now I'm faced with a site that has a lot of tall skinny images. Most of them require scrolling when resized like that. I'm fine with some vertical scrolling in 800x600, but not so much for 1024x768.

Would you get irritated if you have to scroll to see the big picture? How would you guys attack this issue?
