Completely disagree.
It is not about size it is quality of the image ATk vs sites like Metart Femjoy MPLstudio if you compare the images ATK images are 40% to 60% worse quality.
I get what you're saying, but I think using ATK as an example doesn't fit. ATK has always been for the amateurish vibes while the 3 studio's photography you listed were always at a different level. Just my opinion, but I'm quite happy with ATK photo quality and resolution. I compare ATK to Cosmid which is also pretty good.
