Please notice that the images appear correctly here:
http://www.iconico.com/colorPro/gettingStarted.aspx
but not here:
http://www.iconico.com/colorpro/gettingStarted.aspx

This is because the HTML pages do not require the URL to have all letters in the correct case but the images which will be rendered do require all the letters in the URL to be in the correct case. The difference between the above two URLs is that the first one has “colorPro” whereas the second one has “colorpro” (notice the P).
