problem with images on subdomain

heya folks.

so ive set up a wordpress site on my domain, and ive created a subdomain with a second identical wordpress installation (basically just copy pasted the main wp installation into the subdomain)

and everything works fine except for one thing, that the featured slider (which is set up for showing pages) will not display the featured image that ive selected for those pages that are in the featured slider.

It works on the main domain.

ive noticed that on the main domain, the image patch is:
http://test.anamediatest.dk/wp-content/uploads/et_temp/(image file)

and on the subdomain the image patch is different, it uses home/anamtest/public_html/test/wp-content/uploads/et_temp/(image file).

ive been looking for a solution for a couple of days now, and ive had no luck so far.

thanks in advance.
