- I have a serious complaint...can someone please ask Nancy McDonald to minimise her images as they are, seriously, HUGE! So huge that each of these images takes up the whole screen. If she could lower the resolution of every image she took of her irises from now on...that would be great! I cannot get in contact with this person but if someone could let her know..that would be great -- Main.firecentaurr - 01 Dec 2022
