Click on whatever you want on the left sidebar and you will see the images.
IT'S A VIEWER?
It's more than that. You can import/export images.
how i can import / export images?
I'm sorry I do not understand it..
try inserting the image, but the npc was not updated on the server
Have you tried to do anything or you're just asking to ask?
It's not like you're doing nuclear physics. Click on Image -> Export to export. Click on Image -> Import to import. Then File -> Save (I'm not sure this is needed ).
I am learning and I have mistakes, I cannot place npc above 100.
