I am trying to upload artwork but a lot of what I do is vertical artwork instead of landscape. When I upload it on instagram on the preview, it cuts off the top and bottom. I try to resize it small but it doesn't work. Can't crop it either because then half of the image is done. Can someone please help me. This goes for Twitter too, the thumbnail cuts off the tops and bottom of the image. I don't want half of the image cut off. For example if I do a full pose of an individual, the head and feet do not show in the thumbnail, just the bodice and probably bit of the thigh regions.
