for the shopping cart, i think it's behind the scenes in widgets and activate in facebook.
your image may be too small for even a card.
you can't have that copyright at the bottom, besides being ugly, it won't print. sign your name in cursive. the image is far too small to be of use to anyone. scan these all in. selling these card size - first cards don't sell that often. second you get far less keywords.
choose your best one of these and post that. this one isn't it though that blob tree doesn't attract. you have hardly any keywords. you don't need to tell people your gear, it's better to focus on the location and what we are looking at even if it's obvious because google picks up on it. your far too expensive. no one will likely pay $78 for a small print. further the card is only $5, so i would get the card, you would make a dollar, the card and poster of that size are only an inch apart. people buy the card as a small poster. the current poster price may scare some away. start low and work your way up.
really try to avoid putting the same images into different galleries. if people think they already saw them, they will move on. i recognize half of these. if you don't have enough for 2 folders put them in one, keep the australia part and put it all in there. or break it up to land/sea scape and animals.
i'm on the fence if they will print this with the giant name and date on the bottom.
your bio is very wordy and too show offy. it seems to outline a book you wrote more than the art you make and are presenting. it mentions healing and such a few times. telling us you don't edit isn't a selling point. most buyers don't know the difference, and it really shows a lack of skill. everyone edits and there is nothing unnatural about it. the camera can't pick up what the eyes see as well as you can. and brightening and adding things makes the image taste better.
knowing about your family and where you were born - not needed. overall keep it simple, one small paragraph that outlines what you specialize in. painting i guess wild life and photography with scenes of australia. you can save the bio as an introduction for a review or something. you don't want to bore anyone with a lot of reading.
