Header image not showing anymore

Hi,
I had a header image on my website which was showing fine.
My homepage was http://www.blarneyphotographyclub.com/wordpress
but I moved my files so it would be http://www.blarneyphotographyclub.com
but now I am having problems showing the header image I created.

Everytime I try upload it, it now doesnt show in the preview on the ‘custom header’ function on wordpress.

When I viewed the source code of the homepage the image name reads incorrectly.
Now its banner-head-1-copy1.gif but the image is not saved as this.
I am totally lost and would like to get it fixed as soon as.

Hope my explanation makes sense
all advice greatly appreciated.
