CMS Titleimage image path broken
 

When placing an image path for the title image it forced me to use a full url
http://www.mysite.com/forum/images/skins/image.png (ignore this link the editor refuses to allow me to remove the link)

all other images paths (so far) in my admincp allow me to use short url
url(images/skins/image.png)

is there a fix for this? I know since the full url works this is not a priority however If I decide to change another image path and run into this problem it may cause issues elsewhere

Please excuse me if my terminoligy is not exact I am not a pro at this still learning.
