I found two high quality wallpapers of both halves of the Ruins of Kunark box art. I was able to combine them using Photoshop with good results. The right half had to be a little cropped to make the images fit. However, I'm pleased with the results. Below is a link to download it if anyone wants a copy.

I also found this HD copy of the original load screen.

Remember, I'd still like high quality copies of other box arts, load screens, etc.
