When you fill out the upload page, you will see icons for drawing, painting, sculpture etc etc....pick one.
Then to display the images, you display images and you can put them into galleries. When you upload an image you
choose what galleries you want to enter the images into again on the upload page.
Addition I see you have done those things. I do not know what you are asking.
Do you mean "Subjects", "Collections" or "Products".....???
