An item's main picture is what shows up in the item search result. If a picture is selected when adding an item, the picture is used as the main picture for that item by default. Otherwise, the first picture added to an item will be used as the main picture.
If you have added multiple pictures and want to change the main picture for an item, go to the item page, then tap the icon to the right by the item name. All the item pictures are listed here. Tap the Use as main image button under the picture you want to use as the main image. You can also add a new image to use as the main image by tapping the icon in the upper right corner.
