Hi I am trying to upload some props to the marketplace but am having some trouble getting the pics to upload. I got the thumbnails to work but can't seem to get headers or extra images of my content to upload. I set the image size to what i am supposed to but it keeps telling me its wrong. Not sure what I am doing incorrectly. Here is a tree prop I just uploaded  TREE 003 - Cartoon Animator/scene - Reallusion Marketplace
