No pictures of offspring on a proven breeder?

I saw a snake on KS that I really like, and he's advertised as a proven breeder. I'd really like to match him up with my girl Valentine late in the season (after quarantine), but when I asked for pictures of his offspring, the seller said he didn't have any. Is that weird? Should I be suspicious? Or are most breeders more nonchalant about their babies than I would be?

I don't think it is that odd, especially if they are normals. I have had quite a few normal ball females that have given me clutches. I may take pictures of the babies, but I do not keep track of which female gave me the clutch. This may be especially true for someone with a lot of normal females.
