You have the suffix for your image filenames, '.gif', included in the array; but, then you add it again when you create the shields. The shields will then try to find the filename with two suffixes, '.gif.gif'.

In fact, the 'shields' array is an array of GreenfootImage, not of String. So this line: 
 Shield shield = new Shield(shields[i] + ".gif");
... should not actually compile. Since you did not post the code for your Shield class, I don't know whether the constructor expects a string or a GreenfootImage parameter. Please use code tags to avoid the formatting issues that you have in your post.
