[Theme: Delicate] Image header probs

First of all I admit it: I screwed it up. What’s the deal? I’m using the Delicate theme. You can visit my page @ http://parck.net/

I uploaded several images as a header, soms today and soms a week ago. The images are in rotation. The images are uploaded in the folder wp-content/uploads as 2012/01/a.jog, 2012/02/a.jpg etc. I deleted some images from the folder 2012/01 on my server and NOT by the WP dashboard.

Now these images stay as a ‘dot’ visible in the menu and as a ‘white page’ on the site. You see as you refresh the pas several times.

Anyone knows how to solve this? I looked in several .css and .php files, but I cant find any line that refers to these images.
