Page 249 There is a glitch in 3ds Max 2020. In the UV Editor window, when you are changing the background image, the new image may not appear. If you go back to the drop down menu, just under the "Pick Texture" selection that you clicked on is another selection, "Remove Texture." Select this and your image will appear.
