The bottom one replaces the image that you have in the box and the top one is a new image all together so you can still keep the first image in you image history.
hope that makes sense
Thanks for the reply…so if I’m changing out a texture I can use either one. But which one SHOULD I use? I assume top one, in case I want to switch back?
I would use the top one if im not planning on using many images so i can easily access them when i want but im using a lot of textures and maybe im lazy and dont name them properly ill use the bottom one to replace them so it doesnt get too messy
