So if I have a bunch of art for my pet were could I put it all but still have it on her profile so people can look at it

You could just put the img code for each image in the pet description under the story or make a new textbox to put the codes in.

another thing I've seen people do is have the art set to be seen by clicking links and giving a description on those links like clsoe up or full pose or whatever to describe the pic linked
