Website Performance

Hi,

My website is up and running. When i check the load time with pingdom i get the result that these 2 links are giving a problem.
Also the links are broken apparantly and they cause the site to load 1,2 seconds longer :O

Now i dont know can i just go and delete the files or will this cause problems to the website?

Kind regards,
