# Switch an Item's Primary Image

This endpoint allows you to change an item's image to one of the other images provided upon mint. This feature may be used to update an item's state (i.e., the image can reflect an item's wear, evolution, type, etc.)

Every item has an `imageIndex` property. This property represents the index of the selected image amongst all the provided images. Every item also has a`imageCount` property that represents the total number of uploaded images.
