Do you have confirmation on the FLAT4's surnames? Because if you don't, then you shouldn't be trying to add surnames to them. Surnames for the FLAT4 are purely fanon until official material gives the such surnames.
I'm sorry to tell you this but you're putting way too many unneeded pictures here- especially on the side characters pages- personally i don't think they should have a ton of pictures, the point of them is to see how the character looks like and that is all.
One more thing, if i removed a picture it's because of a few things: the picture has either way too many characters(even 2 characters can be a lot, depending on the position of the characters- if you understand what i mean orz;;), the picture is repetitive(there is the same picture on another characters page) or the quality of the image is low. Please don't add the picture back after i removed it.
Fanmami is a great place with pictures, so if you need some you can visit that site.
