No one can really answer that for you except the Consular Officer who will be looking at them.
ONE photo of the two of you together can be enough --- if that photo, along with your other evidence, convinces the CO that you are worthy of approval.
On the other hand, if you have 10 photos of YOU standing outside the Kremlin, and 10 photos of HER standing outside the Kremlin and NO photos of the two of you together -- then the photos are absolutely worthless as evidence.
Don't focus on the number of photos--- but what do these photos say to someone looking at them.
A photo of you and her together(shows that you've met but doesn't prove much more)-- good
Photos of you and her together at different places(shows that you spent at least a little time together)-- better
Photos of you and her together at different places during different trips (indicating that you've met more than once)-- even better
get the idea....
Photos of you and her together with family are also very good -- gives at least some indication that you have a serious relationship.
Again, focus on what the photos say about your relationship to someone looking at them for the first time.
For both our K-1 and CR-1 interviews, my fiance (and then wife) took about 20 or so photos with her. In both cases, the CO only looked at 1 photo and then told her she was approved.

If I read your post correctly, you've had no direct communication with the Consulate regarding wanting you to return -- only what your fiancee has relayed to you.
If that's the case, the FIRST thing you need to do (and should have done already) is contact the Consulate (call or email) and find out what THEY say regarding wanting you to come back.
Moscow is generally a fairly easy consulate and in almost a decade of following the activity of the Moscow consulate I've never heard of them requesting the US citizen to come in for an interview for a K-1.
