Hi jilalf and welcome to Moon Zoo!
If you find any more damaged images could you please report them to us so we can look into it and fix any possible problems.
You can do the following to get the information that we require:
When you see a damaged image, finish your classification for the pair of images and then select "My Moon Zoo" at the top of the page. This will display the "My Moon Zoo" page which will have two columns at the bottom labelled "Favourites" and "Recents".
Click on the top link under the "Recents" heading. This will be one of the two images you have just looked at in Boulder Wars. If it isn't the damaged image then close it and click on the second link.
Once you've found the damaged image, click on the "view more information" link which will open a new window showing further information about the image.
Copy the information on the right-hand side of the window and paste it into a post on the forum - it should look something like the following:
Sun Angle: -76.23°
Scale: 0.50 meters / pixel
Zoom Level: 3
Anyway, enjoy your time on the Moon
