You paid her for the use of her pics,now she's annoyed about her name being published,even though she's had these pics published for a number of years now.
Simple,tell Hubby that you'll remove the pics if it's causing offence,but he'll have to return the modelling fee.
She happily took the cash,then spent it,if it's so important then let him return the cash.Why should she profit out of your genorosity?
I've had it with a girl here in Ukraine,she soon shut up when the cash was mentioned:)
