Because its becoming a major issue with DH.
I've always hated having my photo taken (take after my late Dad) - very few exist of me.
I hate it even more when I'm fat, as I am at the moment (size 20).
I will not let DH take photos of me. Full stop. Period. End of.
We're going on a major holiday in a month or two and I know it will end up in several arguments.
I just hate it.
