This alt text still says "Ljubljana", which isn't terrible, but the fact that this image is so large is sorta a problem visually. If you adjust it to a width of 590px like Ljubljana's it will look a lot better. Here's what it looks like now. I don't recommend leaving it like that. (I'm not sure how to override the width in webby, but changing the image will definitely work.)
