Should I send more photos or stick to the excuse that I've now used? 

If you still have the broken bottles they wanna see, go for it.
I feel your concern, take your time to make sure it's physically-accurate & believable.
They are probably suspicious, yet asking for more pics is a good sign imo.

If it may bring you some perspective :
I'm currently fighting a store which straight up told me my pics are physically-inaccurate. 
(these guys... successfully hit 3 other stores with the exact same pics lmao )
