Great pictures of your family!
Home buying and selling is an emotional process and as a professional home stager one of the first steps I tell my clients is to "emotionally detach" from your home, make it become a house = product to be sold like any other on the market.
Personal items such as photos, name tags/artwork, diplomas whatever it may be keeps your home YOURS still and buyers do see these items as YOURS not theirs.
Another reason I tell my clients to remove photos, names on art, calendars etc. is for security. A number of people will be viewing your home and personally I don't want my children's identities involved in the selling process. So for this reason alone most people agree.
A suggestion for you though is to replace the current pictures with more generic ones as you are right, you don't want a bare wall necessarily where that space is (I can't tell from the photo). Maybe you have other artwork in the house or you can find something very inexpensively at places like Marshalls or TJ Maxx.
