The SKS originally featured an integral magazine. The rounds were placed on a special type of clip called a stripper clip, and were loaded into the magazine from there.

I'm not expert, but that rifles appears to have an AK magazine attached in both pictures. So you should be fine. The SKS takes either AK style magazines or stripper clips, there are no other options. So if it features a detachable mag, it's AK style.
