Donor sperm

My husband and I had to conceive via IVF using donor sperm as his sperm was not viable. 
I was making a sibling registry on the donor site and reporting a pregnancy and came across we could purchase photos of our donor as a child. 
I would like to make this purchase, as I'm curious, but I don't want my husband to feel like this child is any less his. 
Any suggestions on how to approach this? Or should I just let it be?
