A. Ensure that you are using a high-resolution camera or smartphone to take pictures of your items. Use natural lighting to enhance the quality of the images. Avoid using flash, as it can create glare and distort colors. Take multiple angles of each item to provide a comprehensive view.
B. If you are uploading images from a computer, make sure the files are not compressed or resized too much. Use photo editing software to enhance clarity and brightness before uploading.
