A problem has arisen. I cannot insert an image that would be displayed when SELECTING a map in the main menu. I searched on the forum, found a relevant topic, but there seems to be an error in the instructions. Specifically, when adding it in the branch thumbnailImages -> Add -> New, the last option is missing, which is where the code should actually be written. Perhaps someone could share the instructions and also update the topic?
