7020 sd image with oscam

hi guys
i have an original 7020s and want to use it just as a server for a sly uk card and would like to use oscam.
i am confused as in i have seen images for 7020 HD in the enigma 1 section,can i use these images on my 7020s sd box or can someone advise on which image will let me download oscam,i am not worried about anything else just using as a server,maybe with dydns also would be good.
cheers Baz

Thanks mate much appreciated :09:
