Hello and welcome on board.
The diagrams on your homepage are all courtesy of Steven O'Hanlon. You should remove those links. Deep linking into another homepage that doesn't belong to you and not even giving proper credit is considered bad.
Well then you need to add an additional link to the homepage and tell explicitly that those are his designs. I guess then it should be okay.
Additionally you could also ask the designer for permission.
PS: The panda is by Anita F. Barbour and at least Anita is standing big on the diagram itself.
